Many scientists think the same way you do, and it is being studied and attempted at many places worldwide. Currently, most people studying this are attempting to encapsulate islet cells from pigs then transplant them into pacnreatectomized non-human primates (baboons). I am not directly invovled in this reasearch but I think the challenge relates to finding the correct encapsulation material. Because the researchers in the United States have to answer to the FDA it will probably be a while before this can be used in humans, but it is what many scientists are trying to do.
We are also trying to transplant pig islet cells directly into humans with the use of immunosuppressive agents. Most of which are still in research development but don't seem to have the same side effects as current immunosppressive medications (namely islet toxicity and kindey damage).
