Promises and Dangers of Stem Cell Therapies | Daniel Kota | TEDxBrookings


I’m here to tell you that stem cells are

I’m here to tell you that stem cells are probably coming to a clinic near you but

probably coming to a clinic near you but

probably coming to a clinic near you but that’s not necessarily a good thing you

that’s not necessarily a good thing you

that’s not necessarily a good thing you see whenever people find out I’m a

see whenever people find out I’m a

see whenever people find out I’m a scientist do you usually ask me how’s

scientist do you usually ask me how’s

scientist do you usually ask me how’s this whole stem cell thing going and

this whole stem cell thing going and

this whole stem cell thing going and I’ll be honest with you I for the

I’ll be honest with you I for the

I’ll be honest with you I for the longest time I had no idea how to answer

longest time I had no idea how to answer

longest time I had no idea how to answer that question you see I’m from Brazil as

that question you see I’m from Brazil as

that question you see I’m from Brazil as you can tell and and we and you and your

you can tell and and we and you and your

you can tell and and we and you and your birds in Brazil when you tell people

birds in Brazil when you tell people

birds in Brazil when you tell people you’re scientists there’s there’s no

you’re scientists there’s there’s no

you’re scientists there’s there’s no follow-up question there’s only this

follow-up question there’s only this

follow-up question there’s only this look on people’s faces you know it’s a

look on people’s faces you know it’s a

look on people’s faces you know it’s a mixture of sorrow concerned a little bit

mixture of sorrow concerned a little bit

mixture of sorrow concerned a little bit of disappointment you know it is really

of disappointment you know it is really

of disappointment you know it is really the look of a father whose daughter just

the look of a father whose daughter just

the look of a father whose daughter just brought a boyfriend home and it’s going

brought a boyfriend home and it’s going

brought a boyfriend home and it’s going of all the choices out there I mean

of all the choices out there I mean

of all the choices out there I mean that’s what you decided to go with and

that’s what you decided to go with and

that’s what you decided to go with and and yes and so I stuck with science and

and yes and so I stuck with science and

and yes and so I stuck with science and I was really fortunate to have the

I was really fortunate to have the

I was really fortunate to have the opportunity to come to this great

opportunity to come to this great

opportunity to come to this great country and for the past 10 years I have

country and for the past 10 years I have

country and for the past 10 years I have immersed myself in stem-cell research

immersed myself in stem-cell research

immersed myself in stem-cell research now that the but in here people are

now that the but in here people are

now that the but in here people are really interested in science right but

really interested in science right but

really interested in science right but like everything else nowadays the only

like everything else nowadays the only

like everything else nowadays the only time people are really interested in

time people are really interested in

time people are really interested in science is in social media discussions

science is in social media discussions

science is in social media discussions isn’t it in social media discussions

isn’t it in social media discussions

isn’t it in social media discussions science seems to be such a winning

science seems to be such a winning

science seems to be such a winning argument I mean if you drop a scientific

argument I mean if you drop a scientific

argument I mean if you drop a scientific fact then you basically win the

fact then you basically win the

fact then you basically win the discussion right which is basically why

discussion right which is basically why

discussion right which is basically why we have discussions anyways I guess but

we have discussions anyways I guess but

we have discussions anyways I guess but as a scientist that has always baffled

as a scientist that has always baffled

as a scientist that has always baffled me okay because if there’s one thing I

me okay because if there’s one thing I

me okay because if there’s one thing I learned in science is that David premium

learned in science is that David premium

learned in science is that David premium was right when he said the more we know

was right when he said the more we know

was right when he said the more we know the less we know and the less we know

the less we know and the less we know

the less we know and the less we know the more we think we know so quite

the more we think we know so quite

the more we think we know so quite honestly what people want to know is

honestly what people want to know is

honestly what people want to know is when can I go to the doctor get some of

when can I go to the doctor get some of

when can I go to the doctor get some of it simply and it’s fair and I think

it simply and it’s fair and I think

it simply and it’s fair and I think there’s only one way to describe the

there’s only one way to describe the

there’s only one way to describe the current situation we find ourselves in

current situation we find ourselves in

current situation we find ourselves in as it relates to stem cells and that is

as it relates to stem cells and that is

as it relates to stem cells and that is to say we have reached a critical point

to say we have reached a critical point

to say we have reached a critical point in the history of stem cells

in the history of stem cells

in the history of stem cells a point that can only be described as

a point that can only be described as

a point that can only be described as this what you see is a massive number of

this what you see is a massive number of

this what you see is a massive number of different stem-cell treatments out there

different stem-cell treatments out there

different stem-cell treatments out there and really the only thing between them

and really the only thing between them

and really the only thing between them and us our regulatory agencies such as

and us our regulatory agencies such as

and us our regulatory agencies such as the FDA in the US but the number of stem

the FDA in the US but the number of stem

the FDA in the US but the number of stem cell treatments out there are getting so

cell treatments out there are getting so

cell treatments out there are getting so overwhelming the some are just falling

overwhelming the some are just falling

overwhelming the some are just falling through the cracks and the question then

through the cracks and the question then

through the cracks and the question then is how did we get here and what does

is how did we get here and what does

is how did we get here and what does that mean to you so the first thing we

that mean to you so the first thing we

that mean to you so the first thing we have to understand is that stem cells

have to understand is that stem cells

have to understand is that stem cells really exists within a relatively large

really exists within a relatively large

really exists within a relatively large spectrum okay it starts with your

spectrum okay it starts with your

spectrum okay it starts with your embryonic stem cells goes through your

embryonic stem cells goes through your

embryonic stem cells goes through your postnatal adult stem cells all the way

postnatal adult stem cells all the way

postnatal adult stem cells all the way to adult cells that we can now it

to adult cells that we can now it

to adult cells that we can now it genetically reprogrammed to become

genetically reprogrammed to become embryonic like stem cells we call those

embryonic like stem cells we call those

embryonic like stem cells we call those induced pluripotent stem cells or iPS

induced pluripotent stem cells or iPS

induced pluripotent stem cells or iPS cells now we knew from the beginning

cells now we knew from the beginning

cells now we knew from the beginning that embryonic stem cells offer perhaps

that embryonic stem cells offer perhaps

that embryonic stem cells offer perhaps the greatest differentiation potential

the greatest differentiation potential

the greatest differentiation potential which is by the way what defines a stem

which is by the way what defines a stem

which is by the way what defines a stem cell is a cell that can replicate and

cell is a cell that can replicate and

cell is a cell that can replicate and giving the right cue it can

giving the right cue it can

giving the right cue it can differentiate you to something else

differentiate you to something else

differentiate you to something else hopefully something useful but we’ve

hopefully something useful but we’ve

hopefully something useful but we’ve always known that great differentiation

always known that great differentiation

always known that great differentiation potential also means the greatest risk

potential also means the greatest risk

potential also means the greatest risk and it’s a very simple concept to grasp

and it’s a very simple concept to grasp

and it’s a very simple concept to grasp right we tell our kids I tell my kids

that’s the last thing we wanted now as I

that’s the last thing we wanted now as I speak and I say in an upset a lot of

link said I have to tell you that both

link said I have to tell you that both embryonic stem cells and iPS cells

embryonic stem cells and iPS cells

embryonic stem cells and iPS cells represent a very small fraction of all

in going in we knew that adult stem

in going in we knew that adult stem cells have limited differentiation

physician in that case decided well let’s go step further and inject these

let’s go step further and inject these

let’s go step further and inject these cells inside our eyes directly into

life and what’s worse about this case is

life and what’s worse about this case is that the physician he had the trouble to

that the physician he had the trouble to

that the physician he had the trouble to go to the FDA and start a clinical trial

go to the FDA and start a clinical trial

go to the FDA and start a clinical trial so he could falsely advertise that his
