> patient's own stem cells

> immunosuppression would not be required

I don't think that's how Type I Diabetes works. People get Type I Diabetes because their immune system attacked their own insulin producing cells in the first place. It's an autoimmune disease. So if you replenish those cells, they'll just get attacked again.

Possibly, it is defo important to keep tabs on how these patients fare after a few years. before we rush to ship this

From above link:

>A 25-year-old woman with type 1 diabetes became the first person to successfully receive a transplant of insulin-producing cells derived from her own reprogrammed stem cells

There were these studies where t1d patients immune system was "restarted" and they became insulin free. https://pubmed.ncbi.nlm.nih.gov/17426276/
