What Is the Current State of Stem Cell Therapy in Diabetes?

Diabetes mellitus is a chronic and progressive metabolic disorder associated with abnormal blood glucose levels. The term involves several diseases with different pathophysiology mechanisms and treatment strategies. Stem cell-based treatments represent an emerging strategy for patients with diabetes mellitus with severe pancreatic insufficiency and poor glycemic control. Over the last 20 years, researchers have investigated mesenchymal stem cell infusion and the transplantation of stem cell-derived β cells and islet tissues. This review aims to comprehensively discuss the latest advances in the field of stem cell use in diabetes, including clinical studies and preclinical experiments aiming at improving the efficacy and safety of stem cell use.
