Dr. Paul E. Lacy, a pioneer in the field of islet cell transplantation and one of the foremost experts on the subject, said there is no question the monkey findings have buoyed islet cells research in laboratories throughout the world. The obvious next step is to try the drug with humans, he said. The question is not only whether the drug will stop the rejection of transplanted islet cells but also whether it will stop the body from attacking the new cells. Where nondiabetics have an automatic system for sensing levels of glucose, or sugar, in the blood and delivering the appropriate amount of insulin, diabetics have to manage blood sugar on their own. Theirs is a life of following a strict regimen and constantly being aware of everything that affects blood sugar.

Insulin or oral diabetes medication brings it down. Stress drives it up. Exercise can bring it down. Illness, even a slight cold, can send it up again. Most people cringe at the thought of giving themselves shots every day, but that is not what bothers Edgar, who was diagnosed so young she doesn't remember not having daily injections.
