Islet transplantation: current status and future directions

Pancreatic islet transplantation has gone a long way to finally enter the armamentarium of today's clinicians for the battle against diabetes. The proof of principle has been made and current clinical islet transplant trials need to further refine this attractive treatment modality. We review the post-Edmonton era, the selection of islet transplant recipients, the production of islet grafts, and the need for immunosuppression and procedure-related risks. The success of islet transplantation and expansion of clinical trials with islet networks are also discussed.
