The first story by far intrigues me! If they can stop the destruction of the Islet cells there is a possibility they can stop the diabetes! I believe Dr Denise Faustman has been working on this at Massachusetts General Hospital with some success! This excites me very much. The islet cell transplant so far requires anti-rejection drugs that are almost as bad as managing diabetes with the methods we have now. If they can get beyond the need for anti rejection drugs, then they are making progress!
Skin stem cells turned into Beta cells that produce insulin. That means no anti-rejection drugs and an unlimited source of beta cells, that is a cure!
The only thing in the way at this point is getting a higher ratio of skin stems cell to evolve into beta cells in the lab. It has worked in mice extremely well.
