Something isn’t right with this article. I’m suspect:
Type 1 is where your islet cells die off and you lose insulin production. Type 2 means your insulin production is fine, but your cells are resistant to the insulin. A Type 2 should have plenty of islet cells so adding more doesn’t seem like it would do anything. Your body should regulate those cells to output the same amount of insulin as before.
This same treatment has been done in Type 1s already. It’s not new. The problem is their body eventually kills off the transplanted cells and you have to do it again. Plus, you have to take immune suppressing drugs forever.
“Despite a kidney transplant, his pancreas still doesn’t produce insulin.” - This is just nonsense.
