Actually, I've read e-mail from the first successful human implant of
donated Beta cells micro-encapsulated in artifial cell capsules. He lived with
it for several years, but, as expected, the cells have been dying off slowly.
Trouble is that the membranes that protect the Beta cells have no exttra
room in them for replacement cells to grow to replace what dies off naturally,
as body cells always do eventually.
Unfortunately he committed suicide recently for a variety of reasons. You
can find information about this at the following webpage:
