My sense is that he followed the basic science, working deeply in stem cell biology and adding significantly to our knowledge. This is another important route to convincing people that they should pursue something like stem cells - if you know how they do what they do, then you can make educated guesses about how to prevent side effects, too. So, to the contrary, I think he's done many things over the past 10 years t…
Do you think his research will result in type I diabetes being cured in humans in our lifetimes?
A therapy that's as good as a cure (such as one that is stem cell based, or otherwise) does seem likely in the next 15 years to me. I've worked on this problem briefly; my role was miniscule, but the basic idea is that you can encapsulate beta cells in an artificially immunologically privileged space, such as an alginate capsule. If done just right, this will let you sense glucose, secrete insulin, and avoid immune attack.
At any rate, yes, I think that we're getting closer to meaningful "post-insulin" therapeutics. Whether or not that will be due to stem cell biology, I don't really know; to be honest, I don't really mind what technique is used so long as it is safe, effective, and maximizes the patients' quality of life.
