This is a bogus article. Type 2 diabetes is not caused by failure of the islet cells but by a loss of sensitivity to insulin in the body. Only Type 1 is due to the loss of pancreatic islet cells.
Maybe - one of the theories of T2 is that the insulin resistance burns out the insulin producing cells because they have to produce so much that they burn out. Replacing those may “solve” the problem.
mmm.. unlimited twinkies.
