One promising way to treat diabetes is with transplanted islet cells that produce insulin when blood sugar levels get too low. However, patients who receive such transplants must take drugs to prevent their immune systems from rejecting the transplanted cells, so the treatment is not often used. To help make this type of therapy more feasible, MIT researchers have now devised a way to encapsulate therapeutic cells in a flexible protective device that prevents immune rejection while still allowing oxygen and other critical nutrients to reach the cells. Such cells…
