“Living drug factories” might treat diabetes and other diseases

Chemical engineers have developed a way to protect transplanted drug-producing cells from immune system rejection. 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 […]
