The major goal of the Emory Islet Transplant Program is for patients participating in this study to be free of the need for insulin injections after 2 islet transplants. Because many advances have been made in islet transplantation, the transplant team at Emory would like to participate in this promising treatment of type 1 diabetes and, most importantly, help those who suffer from this disease become free from daily insulin injections and avoid the devastating complications that happen as a result of diabetes.
