What are stem cells? - Craig A. Kohn

Learn about the science of stem cells and how these incredible, transforming cells could lead to personalized medicine for individual bodies.
--
Is personalized medicine for individual bodies in our future? Possibly -- with the use of stem cells, undifferentiated cells with the power to become any tissue in our bodies. Craig A. Kohn describes the role of these incredible, transforming cells and how scientists are harnessing their medical potential.

I want to learn how to animate like that one day.

[@maryamalbalooshi1634]

Ben Wycherley rude 😂

[@TheQuranStream]

yo go to ted ed about page, and contact them about their animators, when u get their animators contact, contact them for tips

[@zuhadafridi]

Did u learn it in past six years? If yes, then please let me know too

[@rydonwunali]

@@zuhadafridi i learned to do the transitions using prezi for presentations but not really the frame by frame work, if you want i can show you what i did

[@zuhadafridi]

@@rydonwunali plz show it to me. Which country r u from

[@MilanTheAngel]

ok, so stem cells don't do much in their original form, but they can transform into other types of cells... are stem cells dittos?

[@rioperez2115]

Hahaha!

[@501stEliteClone]

+Vegeta *two finger vegeta point*

[@PuffyRainbowCloud]

I think Dittos probably have a lot of stem cells and also the ability to revert the changed cells back to stem cells, somehow.

[@wafl423]

yeah that sums it up pretty well

[@VeN0m88]

Vegeta There spicy nacho dittos

[@magicstix0r]

The liver was a pretty poor choice for an example on regenerative medicine... It regenerates itself already...

[@seknight2835]

yeah they should have chosen brain or heart

[@Kalashnikov04]

Magic Mojo15 got em

[@jezzyby47]

The whole body regenerates itself, but not so well these days. They should be telling us why our bodies aren't performing as well as they could be, not what 'scientists' are doing to help. These same 'scientists' discovered GcMaf back in 1994 and it has been suppressed by all gov'ts since then. They are not performing as they should be due to nagalese which we get from vaccinations. Nagalese cripples our own GcMaf production, that's why it's in vaccines, so you keep having to visit your doctors for more 'disease management', otherwise known as being fleeced by Big Pharma.

[@Derek-d5097]

Okay, I have one question? WHY ARE WE NOT FUNDING THIS?

[@kritarth]

duh , obviously there are much more important things to fund like military and nuclear research

[@calen4546]

[@Derek-d5097]

jeremiah goh. How?

[@thegrimmeater8417]

dude there is this whole controversy and the best way to get stem cells is an unborn feastes and people think abortion is bad so the governments like sorry u only get a certain amount of feates and stuff its just a mess

[@Alex-st1hd]

Thegrimmeater Stem cells are not taken from aborted foetus'

[@zwolfelfen]

In fullmetal alchemist philosopher's stones are made from humans, so are stem cells basically philosopher's stones because they increase life expectancy and are made from embryos which are pretty much babies but unborn.

i'm 5 years late but omg this is the best explanation XD

3D Printing + Stem Cells = no more waiting lines

[@craigkohn]

Hello all! A couple quick responses to some valid questions: -Currently most stem cell therapies are based on tissue-specific (or "adult") stem cells. The treatments are very limited in what they can do (hence the interest in other kinds of cells). -Tissue made from embryonic pluripotent stem cells does face the risk of rejection by your body. This is why there is so much interest in induced pluripotent cells, which would come from your body but have the capabilities of embryonic stem cells.

ok

[@badass_omelette5166]

That’s actually cool

[@theloniouscoltrane3778]

So what. You make your own presentation.

[@SaveTheCordFoundatio]

Love the graphics and the explanation is very clear...but....and this is a big but here... you skipped completely over the fact that you can collect non-controversial stem cells from cord blood at birth without causing harm to the mother or child. You mention embryonic but this is a far more controversial source of stem cells. Why not just use something that we would otherwise throw away? Let's use the cord blood collected just after the birth of a child. Give life twice. Save the cord.

[@ABaez-hb7bf]

This deserves way more attention and likes

[@TheWhiteRhino]

A fetus doesnt show brain activity for 5 weeks, its not alive until then

[@potatoefat940]

just use the embryos left after IVF.

[@chickennugget9412]

absolutely. but i fear ppl are onna complain abt it like the embryo controversy.

[@missstudy1226]

Agreed and that's actually the MAIN positive point today

[@nibrasulhaque9399]

Nice creative approach. Please make more of like this animations,where people can understand complex phenomenons.

2:15 To add to that: For Leukemia, the curative effect of stem cell transplants is actually due to the GvL effect, or Graft versus Leukemia effect. In other words, it's an IMMUNE-based response where the new cells you received (LTCD8, NK cells) are literally directed against your cancerous cells, thus curing you of Leukemia. (or at least that's me summarizing what I understood from today's lesson. I really like your video btw)

it s a really helpfull video to understand the main stem cells science

[@thomasmckonigal4191]

Embryonic stem cells aren't necessarily aborted babies with regards to IVF. If a couple are not able to have a baby they can obtain the necessary requirements for life from donors. The sperms and eggs are brought together in a lab where they form embryos, but say for example 5 embryos were made but the doctor only implants 2 into a surrogate (or the mother) and the doctor freezes the other 3. She falls pregant and gives birth. Now maybe the mother wants more children then she can use the remaining 3 embryos to be implanted in her and can fall pregnant. BUT the mother may not want to have any more children hence she is given the option to maybe donate the embryos to another couple who wish to have a baby but can't OR donate them to science - in this case stem cell research. This is the reason why stem cells is such a controversial topic because the remaining embryos are more or less unborn babies and it may go against the grain of several religions.

[@ivanberdichevsky5679]

Would the turnaround for that be Pluripotent Stem Cells? Or they are not nearly as good as Embryonic Stem Cells?

[@kelechionwuzurike4830]

@@ivanberdichevsky5679 this is 2 years late but Pluripotent stem cells ARE embryonic or from the embryo
