Okay, hello everyone, and welcome to the Museum of Natural History,
and to our Stem Cell Ethics panel.
So some of your faces are familiar, but some are new, so
I just want to give you a little context for our panel here tonight.
So this is part of our five part stem cell course here at the museum.
This is the first year that we're doing this.
And this was brought to you from a grant from
the New York State Stem Cell Science Program.
And we spent a lot of time delving really deeply into the biology and
the complexity of many of the lab techniques related to stem cells so
far and we've talked about induced pluripotent stem cells.
Last week, we talked about embryonic stem cells.
We also had some conversations about human animal chimeras.
And so there are a lot of issues that's we've talked about in depth
from the biology perspective, but we had have not
at all talked about any sort of ethical concerns related to these things.
So I think we have a lot to talk about tonight in our panel.
And so we have a wonderful group of people who are joining us here today.
But before I introduce them,
I'd like to introduce my colleague Dr. Zehra Dincer,
who has been doing a wonderful job as our stem cell educator here at the museum.
But just to reiterate, and give you a little background about Zehra.
So she earned her PhD in biochemistry, cell and
molecular biology from Wilde Cornell, Sloane Kettering.
And her doctoral work focused on deriving precursors of sensory organs and
pituitary hormones from human embryonic stems cells.
She holds a patent for her discovery, and
she talked to us a little bit about it last week.
But she is a little bit too humble about it.
And she is the first person to have ever done what she did before.
So Zehra, why don't you come on up.
>> [APPLAUSE] >> Welcome back everyone.
I'm Zehra Dincer, I'm stem cell educator at American Museum of Natural History.
And tonight, we have our panel discussion on bio ethics related to stem cells and
regenerative medicine.
2:21
Stem cell research offers tremendous potential for biomedicine.
It also raises important ethical and policy challenges.
We are hoping to have an interesting conversation in the intersection
of science, technology, public policy, and ethics tonight.
We are happy to welcome such a distinguished group of
experts as panelists.
Before we begin, I would like to introduce them.
First, I would like to start with Josephine Johnston,
she's coming from Hastings Center.
She's an expert on the ethical, legal, and policy of
biomedical technologies, specifically human reproduction and genetics.
She's a lawyer and has a bioethics Master.
She's also our international expert.
She practice and work in New Zealand, Germany, and currently in US.
I also would like welcome Dr.
Robert Klitzman, he's a professor at Columbia University.
And he's cofounded and codirected the Center for Bioethics.
He's a prolific writer, has written over 120 scientific articles,
eight books regarding bioethics of stem cells,
assisted reproduction, and research ethics.
He also has an appointment with the New York State Stem Cell Commission, and
US Department of Defense.
3:55
And also, I would like to welcome Beth Roxland.
She's an associate at Medical Ethics Department at NYU.
She also legal and health policy consultant.
Beth brings insight from companies and law firms.
Like Josephine, she's also trained as a lawyer and has a bioethics Master.
She has created policy, lecture, and publish on the range of stem cell
topics which we will be talking about in details tonight.
So I would like to welcome everyone.
>> [APPLAUSE] >> So
now let's jump right into our discussion.
Stem cells have been used in medicine since the first
adult bone marrow transplantion in 1968.
And stem cell therapies have saved lives, yet
stem cells have also generated a lot of controversy in the past 40 years.
So why are stem cells controversial?
>> [LAUGH] >> It's a big question and you can.
>> I would say that, or do you want to go?
>> You can start off.
>> Stem cells are controversial because there's a question about
the moral status of a stem cell, I would say.
That stem cells, which as you all know, form when egg meets sperm they create
a cell that then goes to two cells, four, eight, etc.
And many people think that in the United States, it's not my opinion, but
many people do, that stem cells are the equivalent of a human being and
therefore we shouldn't do research on them.
Others of us say that we believe that,
given that stem cells can potentially save hundred,
research on stem cells could potentially save hundreds of thousands of people,
millions of people's lives, that it's okay to do research on them.
But I would say that's, in my sense that's sort of an underlying tension
in terms of why there has been controversy.
>> And I think it's important to point out that you are,
there's something that happens a lot actually is that people
are thinking that stem cells are only the ones from embryos.
So you can get stem cells from any one of us, from your skin, for
those who have taken the class.
But it was after the first time that stem cells were derived from human embryos and
you had embryonic stem cells that you had public debate.
Not just in the US, all around the world about doing that kind of research
using human embryos to create a material that you would use in science and
potentially in medicine didn't sit well with a lot of people.
Some people who think that an embryo is a person but
some people who think that an embryo wasn't a person but
is significant in some sort of way, might have felt some discomfort or
ask questions about research that takes human embryos and destroys them.
And research sometimes that actually makes embryos for
the purpose of them taking the cells out.
And you can't really take the cells out without destroying the embryo.
So I think I don't know if regular stem cell like non
embryonic stem cells have really gotten much public discussion, a bunch attention.
But I certainly think that embryonic stem cells were obviously an enormous issue,
for like a decade.
>> Yeah, no, I agree with, well both but as Josie said, I think there is definitely
a differentiation of the sensitivity of embryonic stem cells versus others.
I think there is though still also the larger picture of playing God,
which we have in science generally.
Because embryos, embryonic, all stem cells with the pluripotent potential,
have so many, are we going to create meat from stem cells,
that aren't embryonic necessarily?
All of the variations and what you can do with a stem cell.
11:43
And that, I think, is where there gets to be debate.
And of course, I think the sort of compromise that was made with research
that is held pretty much is that an embryo up to around 14 days when it's
an undifferentiated mass, is one thing.
Around 14 days, it begins to differentiate, this clump of cells.
At some point this clump of cells becomes a human being.
And at 14 days begins to differentiate,
you have the beginning of a dividing line that becomes,
it's called the primitive streak, and that eventually becomes the nervous system.
And so the consensus has been that up til that point when it
becomes differentiated that it's okay to do research.
That may in fact, I hate the term, destroy the embryo,
but that's really what it's doing.
So therefore, I think people agree at early stage okay for research,
after that more problematic.
>> That's it, great.
So can you please talk about history of political landscape and
policy regarding stem cells?
It's a big question, but
can you walk through Bush era and- [LAUGH] >> You just asked us
what the moral status of the embryo was.
So I mean, this one's actually the softball question.
>> [LAUGH] >> So
I guess the date August 9th, 2001, will be burned into my brain, as someone who's
been following stem cell research ever since I got a Master's degree.
Prior to the Bush administration policy, under the Clinton administration actually,
because they had already isolated embryonic stem cells.
There was actually the formation of a movement to start regulating it,
to start guidelines.
August 9, 2001, President Bush announced in his speech,
it wasn't even an executive order.
Basically, I don't want to say ban.
But that federal funding should only be used for embryos or
embryonic stem cell lines that were already in existence and
approved by the NIH as of that date.
And it's sort of, for people who are into politics, it's actually kind of
interesting that it was this big policy, actually was just verbal.
It was just part of a speech.
It was obviously then moved forward by the NIH, and what have you.
But again, the Bush administration policy was as of the date that he said that,
whatever lines were in existence, it was sort of almost the cat is out of the bag.
The NIH has approved it, but federal funding will not be used for
anything other than those lines.
16:23
Under President Obama, we can now use any kind of embryonic stem cell line but
that could not have been used from an embryo that was created for
the purpose of research.
So we can only be using federal funding for
lines that were derived from clinically excess embryos.
So clinical, IVF, a couple, individual goes to a clinic,
has excess embryos after the fact.
Do they want to donate it to stem cell research?
Lines are derived, federal funds can go to that.
But there was a very clear decision to be somewhat conservative and
not allow federal funding to go to embryos that were created for
the purpose of research.
And there have been, I think there are, and I don't know if you
want to go this far but there are certainly some issues with that.
I think one of the principal issues being, and I'm sure most people will know that
in order to actually go through IVF you need to have quite a bit of money.
And the number over their percentage of leftover embryos,
clinically excess embryos are largely Caucasian and from wealthy folks.
And so to the extent that we are attempting to a further research using
embryonic stem cell lines, we're not going nearly as far as we possibly could be.
Because we're not allowing federal funding for
the creation of embryos that might be for other populations, let's say.
>> I would just add everything Beth said is correct.
One is that when Bush announced his policy at the time,
it was said that there are about 65 lines out there that have already existed.
It turns out the number was [CROSSTALK] 22 or something like that.
Secondly specifically I think that a lot of people hope that Obama would
now allow was to use federal funds to create new lines.
It is one thing to say that there are lines that happen to be out there.
But federal funds can create new lines to include a wider diversity of people,
etc., in terms of the genes involved.
So I think that was something people hoped for that didn't happen.
And I think one that happened as a result of the federal funding is
that states then jumped in.
So you first had California that had decided they
would spend $3 billion, I believe is the amount that they had a proposition,
a bond- >> Yeah they had like a referrendum-
>> Right, and so they decided they would,
as a state, even though you couldn't use federal funds,
California as a state has spent 3 billion.
And then New York State actually decided it would spend 750-
>> 600 million over 11 years,
sorry these numbers are kind of [LAUGH].
>> So that was good.
>> It's like a button I'm like, August 9, 2001 [LAUGH].
>> I mean, one of the things I think is really with us noticing about the way
that this works in this country is that you have a set of rules that
hinge on where your funding comes from for your research, okay.
That is really unusual from an international perspective.
A lot of times people say President Bush banned embryonic stem cell research or
something like that.
He didn't ban it.
It could absolutely take place.
You could do cloning in the United States.
You can make embryos for research from donors.
You can do almost anything, as long as you don't use federal money for it.
The restrictions were about what you could use federal money for.
Now there are all sorts of reasons why there is the mechanism here, but
it's a very unusual approach.
Internationally, the approach is we have a law for our country,
that's the law that's- >> Mm-hm.
>> That's how it all goes, we don't differentiate between things
we use federal money for and things we didn't use federal money for.
So it's a pretty unusual setup
as a way of regulating an area of research or activity.
20:27
The other thing that I think is really interesting, and
if you're a lawyer you can geek out on this, because I did, even before I came to
United States I had already studied, this was like, this is amazingly weird.
Okay, there is a- >> That's
the only thing weird in America, right?
>> [LAUGH] [CROSSTALK] >> There is a federal law
that says you cannot use federal money to do anything harmful to
an embryo at all including make stem cells from that embryo.
But there is a federal policy that you can use
federal money to research those cells once they're out.
So we have the situation where if you've got an embryo left over from IVF and you
want to take the stem cells out, you use private money, whatever your statement.
And then once you've got those lines out,
now you can do research on them with federal money.
And it sort of, I mean, I know someone who is heavily involved in making this policy,
and it's very clear for policy.
But it is a little weird, counterintuitive, right?
Like- >> It was.
>> The federal government's like our hands had nothing to do with
destroying the embryo.
But once you get those cells out, here's the money to do the research.
That is actually- >> That's exactly what it is.
>> It's a very strange approach.
>> And I think it was, and we know it was Harriett Robb who's now at Rockefeller who
actually wrote that opinion.
>> Yeah I read that thing before I even came here, imagine,
I had so much excitement when I met Harriet, I was like wow she's so fast.
>> I was seriously like in awe as if she's like a pop star because I had so
much- >> So
the memo that was written by Harriet Redford Clinton of like
why she thought they could get through the Dickie-Wicker this way.
It's really clear of a law.
But it is also on a kind of intuitive level, takes a wee bit of processing.
And actually the whole thing was challenged in court in 2010 to 2012.
But by then, the federal government had using this approach, where they wouldn't
fund the derivation but they would fund the research for a decade, and the courts
were like, we are not interfering in this interpretation of the law.
You couldn't make it up, it's a fascinating kind of approach to
regulation, and it's a fascinating way through the Dickie-Wicker amendment which
keeps getting added to every appropriations bill, but
still allowing the research to go forward.
And it's the only country I know that's gone even close to a policy like this is
Germany which said for a while, you can't make stem cells from embryos.
But you can import them, and then do the research,
which is kind of the same sort of idea, right, yeah.
>> It seemed, at least on the surface, and I think it still does, an attempt for
the administration to go as far as it can given congressional policy.
>> Yes, absolutely.
>> So that the federal funds are not used in what might be considered abortion, or
anything having to do with destruction of an embryo,
and I'm sorry if I wasn't quite clear on that.
And that's also, in part,
why I think there was some disappointment in the Obama administration policy.
Because even though you're blinding yourself for
the federal funding as to where the stem cell line came from, there was a hope
that the Obama administration would say we'll blind ourselves even if you created
the embryo for research purposes and not just clinically excess.
[CROSSTALK] And it did not go that far.
>> Yeah, that's right.
>> And, of course, abortion again,
is the reason that we have such a screwy system so to speak.
>> No, it's a big part of it.
I mean, yeah.
So I'm wondering about international landscape in a way if any country
is more permissive or less permissive comparing to the US.
>> Well, I think the US is both being sort of simultaneously permissive and
not, right?
So you have these funding rules which are fairly restrictive on their face.
But you also have a background where you don't have national laws on it.
So in some countries like the United Kingdom, or Canada,
or Australia or a bunch of other places, >> Japan.
>> You have national laws that affect stem cell research and
effectively regulate it, embryonic stem cell research.
But at least in the UK, for instance, those national laws allow a lot more
things to occur than the federal rules do here.
So you can kind of have this, it's both more permissive, but also more controlled
because everything is subject to oversight.
There separate tracks for private money, so it's so generous I think.
It's an unusual combination of being both quite restrictive, not at least now,
but still.
And also quite permissive on the other hand,
where it's not the approach taken by other countries.
>> Certainly, and there's also, and you could speak to this as well, international
laws not just on the derivation, but on who can give informed consent.
I remember Japan actually being one of the most interesting ones.
It said that a husband and a wife must give informed consent.
It was not the gamete donors.
But there are international laws regulating various parts of this.
It's not all about just the derivation, let's say, aspect, there's more.
But Josie raised a very good point about
the way the US works which is that a lot of the restrictions are tied to funding.
Such so when Robert is talking about how states started to get into the act which
is a very odd thing in the US.
Most funding comes from the federal government.
But because of the Bush administration policy and the promise of stem cell
research states states started to get into the act, specifically,
of funding stems cell research with the hopes of building enterprises,
potentially, getting license rights back.
But mostly with their hopes of building their own enterprises.
The states have been able to go further than the federal policy.
Which is exactly why they were in place.
And private funding is,
it almost like the IVF wild west because there aren't restrictions.
>> And there is an interesting policy in New York, right?
So New York states stem cell money, theoretically,
I think, can be used to create an embryo from donors?
>> Yes.
>> And then they even allowed for the payment to the egg donor,
which is a whole another topic, so- >> That was my puppy, that was my thing.
>> So yeah, the one thing I do think must be a little confusing for
researchers, right, because depending on where their money comes from and
which state they're in, they can have really different situations happening.
>> Yeah, it's also quite hard for universities, actually.
It sounds like okay, well, it's clear that's state money that's federal money.
But the problem is that the university Columbia,
Cornell, etc, the feeling was when it was decided that we could use state money and
could not use federal funding.
That we had to make sure that, for instance,
no federal funding went into that building or that lab.
So for instance, if federal funding was used to help build the building, well,
that's federal funding being used if you were doing stem cell research there.
27:32
And the feeling was universities took very,
decided to be very conservative about it, just to make sure and be completely
squeaky clean that no federal money was being used at all in this lab.
I just want to point out a few other things.
One is you mentioned informed consent, which is very important.
This was another area where part of the problem that
there is not been further advances, I think, there's been many, but not as much.
Is because the feeling in using stem cells derived from clinical purposes
is that there needs to be very clear informed consent from both the man and
the woman saying, yes, you can use the leftover embryos for research.
And the problem is that there are hundreds of thousands of leftover embryos in
United States.
That because there is not good informed consent for
research explicitly, they're not being used.
The reason is there's a lot of leftovers, because a couple, let's say,
that's infertile may make eight or ten embryos, and
only use one or two and have a bunch left over.
They don't want to throw them out.
The doctors don't want to be throwing away embryos.
What do you do? Do you flush them down the toilet?
These are potential human beings.
You can imagine the uproar.
And so there's been this odd situation there, too.
29:51
How many are really left over?
When do you know that your embryos are left over?
>> So tons are left over.
>> It's very complicated.
>> There's actually many, many.
>> I think it's very complicated and people don't like to make a decision about
what to do with the embryos, so they postpone it for a long time.
Which you could critique there, but on the other hand it's sort of understandable.
It's an intense decision for people.
And so there's so many factors in there that actually it goes back to
a point that you made which is that just limiting ourselves to embryonic
stem cells that come from left over embryos is, in many ways,
a very sub optimal approach from a scientific perspective.
>> And then when you add the fact that there had to have been consent to do
research on top of it.
>> Yeah.
>> Which is also part of the Obama administration, at least by guidelines.
One side point, The Vatican and now The Vatican might have revised the statement.
But I want to say back in around 2010 The Vatican was asked,
basically, what do about frozen embryos.
And this goes to moral status of the embryos and
the fact there are left over embryos.
And The Vatican actually came up with no response.
What they said was, these embryos should never have been made.
The Vatican will not comment on whether or
not it is moral to destroy them for the purposes of research.
Because it's, obviously,
a big sort of moral quandary that we have leftover embryos, let's say.
>> Yeah, no I think we do,
I just don't think that the number is the number that are right now frozen.
>> It was actually quite interesting the Vatican would not really answer that
question because, Catholic, and I am not so I hope I'm not getting this incorrect.
But according to Catholic doctrine the embryo should never have been created.
>> Yeah there is no IVF on Catholic doctrine.
>> So to the question about how many are left over, I don't know the number.
But a state had approached Art Caplin and I actually wrote a long law review
with Art They were a bunch of clinics that were about to go defunct.
And they had a lot of folks with many,
many leftover embryos who had stopped paying.
The state wanted to know whether they could treat it as abandoned property.
And therefore take on the embryos and then donate them to stem cell research.
Because it felt that it was the morally, I guess,
superior way, more proper way than letting them get destroyed.
I mean, it's an interesting analysis, but
even states there were many, many left over.
>> I think there were probably tens of thousands,
I just don't think that it's the same- >> I think it's most.
>> Really? >> So what I hear from IVF docs is
that most of the embryos that they have frozen will never be used.
>> Really?
>> Now maybe that's 60%, but most of them,
the problem is that people have leftover embryos and they will feel ambivalent.
In other words, here's my potential future kids.
Yes, I'm now 45, but maybe I will want another, or maybe I'm 42, or whatever, and
so they feel, well, we don't want to throw these out.
And the problem is IVF clinics will say well, it costs so
much to store them per year.
Couples will stop paying.
And IVF clinics then feel though that we can't quite throw them out.
Because again, it gets back to the moral status.
>> It's an embryo.
>> Are embryos property, or are they like shoes, or are they something else?
And the feeling is that in some ways, they're not just shoes.
But what they are is unclear, so this often comes up.
Also there are debates somewhere in the media for instance, so
Sofia Vergara who's the actress- >> Yeah,
I was going to ask actually that one.
Who get the custody of the embryo?
[LAUGH] >> Yes, right, so
there are custody battles over embryos where a couple will divorce and
who gets the embryos?
And the consensus in courts, which I think is correct,
is that both parties need to agree what to do with them.
So in that case, which got a lot of press, she's the highest paid actress,
she was a year or two in Hollywood, her ex-fiance sued for custody of the embryos.
So you have things like this happening.
You also had there was a couple that died in an airplane crash that was
quite wealthy.
They had embryos in storage.
So, are the embryos the heirs?
There are interesting problems.
And then so- >> Yeah, that comes up quite a bit, yes.
>> Right, so I can adopt the embryos and raise them, do I get the money?
So you can imagine, again, that these are one of the reasons we have bioethics,
because science is presenting us with ever new challenges technologically.
And we're trying to figure out behind trying to catch up,
looking at the ethical, legal, social implications of these new advances,
where we now have these new entities that we have these,
I won't say things, but embryos and what are they?
>> And you raise actually a great point, which is that we talk a lot
about what we do with embryos if we destroy them for research.
But here we have embryos that are potentially left over and
just going to be destroyed.
And no one really talks or regulates that.
And I mean, there's one of the other areas that we had looked
at on this abandoned property question.
We actually went through the entire,
the custody of the embryo during the divorce and how do courts treat it.
Which would implicate the moral status of the embryo, but also things like homicide.
If you kill a pregnant woman, is that two homicides?
Is it one?
All of these sort of legal questions also can affect sort of the ethics and
analysis of the status of the embryo or fetus.
>> There's also interesting cases where a couple will have leftover
embryos- >> [LAUGH] Sorry,
now we're just totally [INAUDIBLE] >> [LAUGH]
>> We're so dorky now, I'm sorry.
>> I'll finish and then we'll go on.
But had leftover embryos, gave them, four embryos or six embryos,
to friends of theirs.
They used two, they had two or four left, they gave them to friends of theirs.
And the first couple said you had no right to give my embryos to that person without
my permission, I don't like that person.
>> Would just say those people have amazing fertility because most of the time
when you give embryos to someone, they use them all up and
none of them can even turn [LAUGH] into babies.
So that's impressive.
>> Part of the issue now is that there's a push to only implanting one embryo at
a time versus two, which was more the norm a few years ago.
36:46
Because of the, at least in the US, funding restrictions,
there was a huge shift towards IPS cells or
disease specific lines, other ways that we might be getting at that.
So it just would sort of know that we should adjust.
I mean, even though the hot topic is usually embryonic,
the fact of the matter is a lot of the research is not necessarily in that area.
>> I'm not sure that we know the answer to your question.
So a lot of the concern about the diversity,
the genetic diversity of the lines, if you like,
has been premised on there being treatments that would be given to
people and how do you make a good match, all those kind of stuff.
And I don't think we are there yet, so we're not at the point where the problem
really becomes apparent how serious that problem is.
That's my impression of the science right now, is that.
>> I agree. >> I think it feels like it will be at
some point some stem cell banks, and they were saying that because America is such
a diverse country, I think 220 cell lines may be covered of whole population.
But for Japan, it's even less because they have a more homogenous population.
So but we are not there yet.
[CROSSTALK] >> Yeah, I think that's right.
And the model that I sort of felt like was going initially with
stem cells was like everybody's going to have individualized lines made for
them that match with them and stuff.
I don't know if that's really the paradigm anymore.
You'll notice that we used to talk about personalized medicine, and
now we talk about precision medicine.
because I think there's been a move away from this notion that each one of us is
going to have treatments personalized to our own make up.
And we can derive embryos from my skin cells and make me special lines.
And I think there's been a move away from that towards something that would be
a little bit more more precise than what we have now.
But not personalized or individualized in a way that we maybe imagined initially.
>> I would say, I think what it speaks to also is there is a tension between
the promise of embryonic stem cells in terms of treatment and the reality so far.
And as in other areas of genetics, we thought that we would be further by now.
And I think part of the tension is because of funding.
I think for NIH to get billions of dollars of funding from Congress and
to get the support of the American people, politicians and
scientists need to say, look, we're going to get treatments out of this.
And the reality is that treatments can take a long time to develop.
So, in some ways, the analogy is if someone asked Christopher Columbus in
1500, what did you find?
He'd say, I found some islands off the coast of India.
And it took hundreds of years to sort of map out really what's there.
Aand so similarly with genetics, the more we learn,
the more we realize how much we don't know in many cases.
40:39
So yeah, if you can create embryonic stem cell lines without involving embryos or
harming embryos, or destroying embryos, whatever you want to call it,
then that would be a way around that particular issue, which is a big issue.
And that's what iPS cells were initially thought to be able to do.
Right? That that would be the solution.
We would just make embryo-like cells out of skin cells and
then we wouldn't need to use embryos.
And so far, I don't think anybody's recommending that we've gotten there yet
and we can abandon embryonic stem cell research.
Yes, so but it's not impossible for
me to imagine a future in which we aren't really dealing with embryos
>> Mm-hm.
>> Anymore.
>> Yeah, so the feeling, so iPS cells is as most of you know, or
you can take skin cells over induced pluripotent cells.
You can take a skin cell and, with chemicals, get it back,
keeping up the form.
>> [CROSSTALK] Send it backwards.
>> Send it backwards to be able to create more various cells.
More skin cells or protect brain cells, the idea was,
it would be great if you could take skin cells, turn them into brain cells into
someone who has Alzheimer's disease or Lou Gehrig's disease, you could sort
of put them in there and they take up, fill in for disease or dead neurons.
The problem is that we're not there with the science yet.
And what happens is they end up forming cancers very easily.
So if you take a skin cell and you put in a few chemicals and
you let it grow in a dish, yes, it will grow.
But it also grows abnormalities, and so we haven't quite figured out how to get it to
grow the good cells, and not have cancers growing as well.
>> So we still need embryonic- >> Yes, I mean [CROSSTALK] think of that,
again- >> It's [CROSSTALK] I think it's in part
because we can't take the adult or
non embryonic stem cells back to a fully- >> Yeah.
>> Nascent state.
>> Yep. >> And the only,
to date, as far as I know,
the only way to actually take it to a truly nascent state is to use embryonic.
>> Mm-hm.
>> We could take more advanced cells and reprogram them back.
They can, they're pluripotent,
they're not- >> But maybe not even as pluripotent as we
[CROSSTALK] >> Exactly, exactly.
>> And people know what pluripotent is, and
omnipotent, so- >> I think our class was really
good at it.
>> [LAUGH]. >> Okay, right.
>> Everybody knows that pluripotent cells
are giving rise to [CROSSTALK] >> We should have
the clicker- >> Yeah,
clicker. >> [LAUGH]
>> Test them on the spot.
Totipotent cells can become everything.
Pluripotent cells can become almost everything, and
more specialized cells can become, you know?
There are heart,
there are blood stem cells that can become different kinds of blood cells.
>> Yeah. >> But they can become
>> Right.
>> Neurons.
>> Great.
So let's change the gears a little bit, and let's talk about some,
we also talk about some recent developments in our class.
And one of them was, this year, we heard the first baby was born
in Ukraine with mitochondrial transfer technique.
And I [LAUGH] you know where I'm heading.
>> Yes I do.
>> Would it be [LAUGH], would it be ethical for
a scientist to try to create babies with three individuals DNA?
And >> So I would say, so
this is, the problem is that the vast majority of our DNA
is in the nucleus of the cell, 99 something percent.
But in a cell there are also these little organelles called mitochondria,
that have some DNA also.
And in a certain percent of people, small percent, less about 1% at most.
They can get mutations and lead to disease.
If you have a mutation, not in the main part of your DNA, but
these little organelles.
So what mitochondrial transfer therapy is, if I have this disease in my family and
it's in these little organelles- >> Or if I do.
You have to be a woman to have it.
>> You need to be a woman >> [LAUGH]
>> But I'm being omni,
whatever here [LAUGH], so right.
So if a woman has this, you could take the nucleus out of
the cell that has these diseased mitochondria, and
put them in the cell, take out the nucleus of another woman's egg.
>> Egg. >> And you can therefore have a, and
the first woman could then use that egg which has her nucleus,
but done under the bad mitochondria.
So research on this was banned in the United States by the FDA,
and it was allowed, however, in Great Britain.
And actually went to Parliament which voted to allow, receive,
just research on this.
And as you say, in Ukraine, there was a birth and
then there was a doctor here in New York.
>> In Mexico, I think.
>> Yeah. >> Right, who did the procedure in Mexico
because it's illegal in the US but not in Mexico and so the baby was born.
So my feeling is that personally that
if this is a way to avoid passing on terrible diseases.
So technically, the baby then has three parents, right?
Because it's the father, the mother, and the woman donating the
>> But at least not call them parents.
>> Yes, correct. >> Okay [LAUGH].
>> Right. So it's biologically connected to three
people though with 99.9% or something, 99 connected really just to
the present connected to >> The mother
>> Quote, mother and father.
So I think that it's unfortunate the FDA has banned research on this.
>> Mm-hm. >> I think that there are reasons that
one needs caution.
In other words, I think that we should be very careful with it,
we should study the outcomes in the child, etcetera, but
that we should to allow, to completely close the door on this is wrong.
And that to allow some research, I think makes sense.
>> But let's not [CROSSTALK] put it on the FDA though.
That's not fair.
So or I'm just being provocative.
>> Right. >> [LAUGH] So
the FDA had an application to do mitochondrial replacement research,
and the point being that it would then develop into an actual treatment.
Someone applied to them and said, can we do this?
And they had a public hearing,
and they asked the National Academy of Sciences to give them an ethics report.
Which is a really unusual thing,
that the FDA does not usually ask about these ethical issues.
And before they could implement the recommendation of
the National Academy of Sciences, we think that we should be able to do mitochondrial
replacement therapy in these cases with people with mitochondrial disease.
47:54
Yeah, the result- >> [CROSSTALK] And then there is-
>> [CROSSTALK] Can't look at this
research, it's not allowed to even consider an application to do it, but
I think- >> [CROSSTALK] And
I think we also need to be clear about how we feel about research in this area and
how we feel about research actually going through potentially not fully
knowing all the effects with a baby born after this.
So how much do we know?
And I think we're covering both, but they are two distinct things.
Should we be doing research in this area and, or
should we actually be going forward with implantation?
>> Right, yeah. >> Actual birth,
it's sort of like a bit of the cloning debate with Dolly.
Dolly looked great.
And then many, many years later, it was, and I'm not saying I'm for or against it.
But we should be clear about the difference between research and
actual implementation in a clinic, at this point.
>> And one of the sad things about this law is that we sort of cut off our nose to
spite our face.
And now that the FDA is not allowed to consider an application to do this kind of
clinical research, people are just going to go and
actually do the thing, not part of a study.
Not research, not overseen by American IRBs.
It's like you make a role that effectively sends
people to Mexico to do their treatment, which really is a predictable consequence.
We are now actually doing it clinically in people.
Versus actually doing it in a more of a research context [INAUDIBLE],
so- >> [CROSSTALK] And
with a country with less oversight.
In many times, with less oversight.
>> I actually like UK's way of doing it because UK
is very often listening to the conversation.
But the way how they tackle the mitochondrial transfer technique is also
very, I think, thoughtful.
They said that you can't have a boy baby because boys,
actually mitochondrial DNA goes through mother to mother.
So we can actually look who's your ancestor just
going through your mitochondrial DNA of the woman.
So it goes all the way back.
So when you have a daughter and do this therapy,
actually you're changing the mitochondrial DNA in a way for the generations.
But if you have a boy, it won't change it, so-
>> It stops with him.
>> It stops with him, so you don't go to the next.
Yes?
>> Children inherit the mitochondrial DNA from their mothers.
But only girls pass the mitochondrial DNA on to their daughters, right?
So mitochondrial DNA follows women, mothers to daughters.
So if you have a son, he would have my mitochondrial DNA, but
he wouldn't pass that on to anybody.
And so that's why they were like, well,
we don't know entirely how this is going to go.
I think it's interesting [INAUDIBLE], but their reasoning was, for now,
let's just let there be sons born.
And then we can see how it goes and then maybe we expand it.
I'm not sure about it, but that was the scientific rationale for the approach.
The UK did this whole thing differently.
They had public debate, they had real discussion in Parliament.
They didn't just slipped something on to an appropriations bill [LAUGH] and
[INAUDIBLE] when no one was paying attention.
It was a wholly different discussion.
>> That never occurs here, I don't know what you're talking about.
>> [LAUGH] >> Jo, I think we're
before the congressional rider.
>> Exactly, no, that's right, so the FDA had its hearings.
But I think they had the hearings because they were like,
this seems like a big deal.
We need to have a public conversation about it.
51:42
But that all got totally usurped.
>> Well, to keep with FDA hearing and Mark Sauer who was at Columbia was testifying
at the hearing and he felt that it was sort of stacked against them even going
into the FDA but- >> No,
people who work in fertility are very sensitive.
I'm sure it was not like a rah-rah, this is all good kind of hearing.
But I think it was actually ultimately would've allowed that kind of a cautious
approach to go forward, but- >> Which is actually interesting in
the IVF context, which is really, really unregulated, as a general concept.
>> Right.
>> Mm-hm, so I'm also wondering about genetic testing of embryos and
also gene editing, at the same time.
Like if we can, because we are running out of time a little bit.
And I just don't want miss all your perspective on that.
So I'm wondering genetic testing of embryos through
a pre-implantation genetic diagnosis to select disease or
eliminate some of them or select for sex.
I dont think it's legal here but- >> No, it's-
>> [CROSSTALK] You can do that.
>> Definitely. >> Absolutely.
>> [LAUGH]
>> You can literally do that down
the road.
>> Really?
>> Sure. >> Yeah.
>> That is what I was trying to say.
Much of IVF is highly unregulated.
>> Yeah, things that are regulated in other countries are totally
unregulated here.
Related to these issues.
>> IVF is generally considered the practice of medicine.
And there's where you've sort of have a very big difference here when we're
dealing with research, besides the fact that there are a lot of federal funding or
funding mechanisms that then have restrictions attached to it.
The practice of medicine is a very different area.
IVF, almost even more so in the sort of lack of regulation.
>> Yeah, so the issue is, so there are a lot of IVF clinics.
It's new, it's growing fast.
It's about 10% of all people are infertile,
all adults throughout the world.
So 10% of couples who want to have children can't.
And you also have women who at 30 were fertile, but
now they've delayed having children.
Now they're 40 and need assistance.
>> And we're still awesome.
>> [LAUGH] >> Yeah, right.
You're not there yet.
>> Bitter.
>> And you also have single mothers by choice, single fathers by choice,
gay couples, lesbian couples, and individuals, etc.
So it's this multi-billion dollar industry.
About 7% of all people born in Denmark,
narrow born using this reproductive technology.
So it's growing, but it's unregulated.
And so they prefer a model of self-regulation, but
there have been problems with it.
>> And other countries have taken a different approach.
So the legislative framework in the UK that allows them to oversee and
regulate embryonic stem cell research in mitochondrial replacement technology also
extends to anything involving experimental embryos.
So it allows for them to create a whole oversight structure that includes IVF and
other kinds of fertility treatments.
And that's actually issue worth pointing out too is that it's good to bear
in mind that IVF is just one kind of fertility treatment.
There are a lot of different fertility treatments.
And more babies are born following other kinds of fertility treatments than IVF.
But IVF is the one everyone always thinks of because it's the most high tech and
the most invasive.
And so the most famous, but it's not the main one, right?
So it's a whole huge, like [INAUDIBLE],
it's a massive industry in the United States and it is largely.
So they're regulated like other.
55:14
Their labs have to be clean, and all those kinds of laws applies to them and
regulations.
But other countries have, for better or for worse, sometimes for
worse, regulated the practice of assisted reproductive medicine.
So they have said things like, you cannot do sex selections with embryos,
you cannot do surrogacy in some countries.
>> Well, it's state by state here for surrogacy.
>> Yeah, and it's different.
But various aspects have been either legislation applying to them,
or sometimes regulations or rules, and And that hasn't happened in the United States?
>> So one of the acutally interesting issues of the parallel of the IVF,
lack of regulation and
the heavy regulation of stem cell research that comes to mind, which is something you
brought up briefly earlier, has to do with the payment of gamete donors.
So in an area where it's permissive, states, Massachusetts,
California, New York, where it's actually permissive to create embryos for
stem cell research, virtually every state, in fact, I don't think there's any state
that regulates the amount of money, in the IVF context, that can be paid to a woman.
We've all read these ads.
College, you play the violin, you're tall,
you're a cheerleader, you can make $20,000, donate your egg.
The states that allow women to donate their eggs to stem cell research,
which is an important endeavor if you're going to create not only embryos but
if you're going to do SCNT and a variety of other kind of stem cell techniques.
Every state except for New York says that you cannot pay women,
56:56
despite the fact that you can pay women 20,000,
unregulated amounts if they showed up to the clinic to donate for IVF purposes.
If they showed up to the clinic and said, I want to donate my egg for
almost the higher purpose of research, states say, the states that
have actually addressed this except for New York, which I'm still very proud of.
States say we will give you your direct expenses and nothing more,
which I think is usually around less than $5,000.
You're literally monetizing- >> $1,000 or something.
>> Mm-hm, yeah, New York being the only state that basically said, we basically
think that it's fair given the number of hours involved, the injections involved,
if the woman is going to- >> It's weeks.
>> And to donate.
And yeah, the reasoning, we took a very long time explaining why it is.
But one of the things that have actually hindered, even state, the states that have
tried to be more progressive with their stem cell research programs, there was,
I think, no egg donors in California at all.
So their attempts to do certain things that were more progressive with the state
funds than with federal funds were stymied by the fact that they could not pay
anything beyond direct costs.
Same with Massachusetts.
I think they had one donor once.
The only state that has actually been successful in it, and
we do have caps, we have oversight.
There's a lot that goes into it.
The only state that has been successful in recruiting women to donate their
eggs to stem research has been New York, because of this compensation policy.
58:30
>> Yeah, great, so if we come back to applications of stem cells, and
I would like to ask two questions.
One of them is, right now, we have this technology creating sperm and
eggs in mice, not in human.
It's not there yet.
But I was wondering, creating sperm and eggs out of stem cells
may revolutionize options for both research and fertility treatments.
And however, what are the special,
ethical issues regarding creating sperm and eggs out of stem cells?
>> So I would say there's a few.
One is, so this is people who are infertile.
Let's say a man can't produce sperm, a woman can't produce eggs.
We take a cell from their body, and do this, create it.
So one is that, as Beth was saying, IVF remains very expensive.
So this is something that basically wealthy
people will probably be able to do, poor people can't.
There are questions, too, we still don't know the safety.
We've been doing it in animals.
It's not yet been done in humans, so there are going to be questions about safety and
risk, etc.
>> And how do you do the research to establish that, I think is a big question.
>> Yes, right, yep, correct, and then- >> And
if you're not mandated to do the research, will the clinics just go ahead and
do the therapy without having to do the research first?
>> [INAUDIBLE] anyway, sorry. >> [LAUGH]
>> And there's also a question, so
if this is how much money we have in the research budget,
in the federal research, most research is still federally funded, I would say, NIH.
And NIH budgets has been flat and President Trump, or
just Trump as I call him [LAUGH] has advocating cutting the NIH budget.
So if we only have this much money, how should we divvy it up?
In other words, should this be a priority?
There are those who say, well, there are children you can adopt, things like that.
These are the ethical issues just that are out there.
In other words, should this be a priority developing this versus other
areas where there are people dying of diseases, etc., etc.?
The other would be just sort of the science fiction side is let's say we
can take someone's skin cell and turn it into eggs and sperm.
Well, let's get someone's skin cells who are sitting in the audience tonight,
they left a cup here or whatever- >> They fell asleep.
>> They fall asleep.
We're all busy leaving skin cells around,
can I develop- >> Like who-
>> [CROSSTALK] Straight out of Law and
Order.
>> [LAUGH] >> So
at some point if this is the technology, can someone get your skin cells and
make basically, have your eggs or sperm in effect?
So these are questions down the line, but- >> And my last question, actually,
I'm wondering about many of our audience actually over the course of four weeks,
they always interested about stem cell treatments and locations.
And I'm just curious when one of the ethical question I come up with with
stem cell treatment was when you are designing a clinical trial,
usually you have two groups.
And one group take the treatment and the other group doesn't take the treatment.
And so you don't tell them, and they are not getting the treatments,
but they don't know about to eliminate the placebo effect on them.
>> It's a double-blind placebo basically.
>> Yes, so what I'm wondering is we will have a speaker coming out for
next week for Parkinson and they are trying to go to clinical trials.
And for Parkinson, in order to deliver this test, you need to do a brain surgery.
And what I'm wondering is you have a person who has Parkinson disease.
And you are trying to do surgery and
you are not telling if you're putting the cells in or not.
And afterwards, you have a control study, which is great on paper.
But, what do you think about ethically?
>> I'll give you a one sentence answer.
I don't think every study needs to be a double-blind placebo controlled trial.
>> Yeah.
>> Right. >> And that's sort of a larger question of
clinical trail ethics in general.
And clinical trials, some of them,
there are some sham surgeries, which is a big ethical issue.
