It takes time (several months) for islet cells to get destroyed by the body. That's the origin of the "Honeymoon phase" experienced by some t1ds after diagnosis. So successful islet cell transplants last for a few months; at the beginning, the patient is nearly cured, and then their islet cells are slowly destroyed by the body. So the appeal of stem cell treatment is that you get a single booster of islet cells every couple months. No nasty immunosuppressants required, because the body doesn't reject stem cells crafted from its own cloth.

Ah if it lasts longer I can see how it would become an option. In my case the "honeymoon" took the better part of a year and if that phase could be repeated it would definitely improve my therapy.
