The simple term “stem cell” actually refers to many different types of cells. The tissue-specific stem cells, or adult stem cells, replenish tissues throughout our lives. Embryonic stem cells exist only briefly in early development before tissues begin to form. Irv Weissman discovered the first tissue stem cells and has helped develop new treatments for disease based on these cells. Weissman has CIRM grant to push embryonic stem cells to form blood and heart muscle stem cells, which could be powerful tools for treating diseases of the heart or blood system. Weissman is Director of the Stem Cell Biology and Regenerative Medicine Institute, Virginia & DK Ludwig Professor for Clinical Investigation in Cancer Research, and Professor of Developmental Biology at the Stanford University School of Medicine.

Dr. Irv Weissman, featured in this video, discovered the first adult stem cells in humans and has developed therapies with both adult blood and nerve stem cells. Weissman supports embryonic stem cell work because of the greater flexibility of these cells.
Embryonic stem cells only exist up to day five in development and cannot come from aborted fetuses. The cells in existence now all came from 4 or 5-day-old embryos that were going to be discarded from IVF clinics.
Adult stym cells are the only 1′s we’ve had real success with. This punks a shill for abortionists.
very very helpful for my essay thank you very much!
this is almost as good as the Tom guy on Cellmedicine channel !
note that Irv is very smart saying that success was in the early phases of trials but doesnt mention that his deal never worked out in the end !!
also interesting how he is stating blood forming stem cells cant make other tissues but he doesnt mention bone marrow or mesenchymals
he is a smart cookie !!
LOL, I’ll bet he is forbidden to inject them into himself but if he was actually growing younger during his employment and became a dashing young man I imagine that would be a dead give away, LOL
I have been saying for a long time that I believe embryonic stem cells to be the true fountain of youth, just think about it, it can regrow new limbs, make a heart normal again, I’ll bet they can and will reverse aging of all cells, not delay aging but literally reverse it
They are grabbing the cells before any formation occurs, it’s not like an abortion where the doctor hacks the baby into pieces. I don’t see the issue, perhaps it is the interference in a life of a baby, so is that any different than banning the experiment and interfering with an adults life to live longer? Is it playing God? Is it not playing God when a paramedic restarts a heart after it stops literally raising the dead? Is it not playing God to take blood pressure meds to live longer?
Yeah. But it would be more impressive if he’d grow himself back some hair for starters!
Finally someone who is not babling about how adult stem cells are the same as embryonic stem cells. I am very happy to see a trained professional speak on the enormous differences between embryonic and adult stem cells.
awesome!
