This is a list of eight studies, which are pretty similar. They all involve using stem cells to treat or cure type-1 diabetes. Some of these studies use adult stem cells, others embryonic, and others cord, although I think the most common is the patient's own bone marrow stem cells.
I consider stem cells to be one possible way to regenerate beta cells. My opinion of beta cell regeneration in general, is that it is not going to cure type-1 diabetes by itself (because the autoimmune attack will kill the new beta cells same as the old ones) but that it might be an important part of the cure. It's importance depends on how fast beta cells regrow after the autoimmune attack is stopped. If they grow back quickly, then no form of beta regeneration will be needed, but if they grow back slowly or not at all, then some form of beta regeneration will be needed. Stem cells are one form of beta cell regeneration, but there are others. Exsulin and human growth hormone have been tested in people, and CureDM's drug in animals, and there are many more.
The good news here, is that there is a lot going on with stem cells, so if we do end up needing new beta cells to cure type-1 diabetes, here are 8 or more reasons why we are likely to have them. And that is not even counting all the non-stem cell technologies out there. But (in my opinion) the "gating factor" (what we in the software industry call the "critical path") to curing type-1 on this path is stopping the autoimmune response, not regenerating the beta cells.
As you read these, you will notice that some of them have end dates in the past, but are still active today. Others have start dates in the past, but have not actually started recruiting patients. These are signs that the researchers have not updated the clinical trial records, and need to. This is quite common. "Primary Completion" is when they finish collecting the data from the patients.
