Islet cell transplantation alone is a powerful but incomplete therapy for type 1 diabetes. When combined with modern immunosupressive regimens, glucose-lowering adjuncts, continuous foremos monitoring, lifestyle changes, and emerging immunomodulatory therapies, it can accere levels of glycemic control andh quality of life that are unatatainatainable by any single modality.
