Diabetes is a complex disease that affects over 400 million people worldwide. The life-long insulin injections and continuous blood glucose monitoring required in type 1 diabetes (T1D) represent a tremendous clinical and economic burdens that urges the need for a medical solution. Pancreatic islet transplantation holds great promise in the treatment of T1D; however, the difficulty in regulating post-transplantation immune reactions to avoid both allogenic and autoimmune graft rejection represent a bottleneck in the field of islet transplantation. Cell replacement strategies have been performed in hepatic, intramuscular, omentum, and subcutaneous sites, and have been performed in both animal models and human patients. However more optimal transplantation sites and methods of improving islet graft survival are needed to successfully translate these studies to a clinical relevant therapy. In this review, we summarize the current progress in the field as well as methods and sites of islet transplantation, including stem cell-derived functional human islets. We also discuss the contribution of immune cells, vessel formation, extracellular matrix, and nutritional supply on islet graft survival. Developing new transplantation sites with emerging technologies to improve islet graft survival and simplify immune regulation will greatly benefit the future success of islet cell therapy in the treatment of diabetes.

Pancreatic Islet Transplantation and Regeneration for Diabetes mellitus Treatment The incidence of diabetes mellitus due to different causes (heredity, unhealthy food, sedentary life style, etc.) is increasing both in Latvia and worldwide every year. In almost all cases insulin therapy must be administered. However, the latest modern technologies promote the development of new and alternative treatments of diabetes mellitus. One of them, the procedure of islet transplantation is comparatively simple and relatively non-invasive in contrast to whole pancreas transplantation. It is considered as a perspective strategy in the treatment of patients with type 1 diabetes, when the insulin-producing beta cells have been destroyed and blood glucose level is above the normal range (hyperglycaemia). Successful outcome of clinical islet transplantation has been shown in several islet transplantation centres in Europe and elsewhere, particularly in the last seven years, using corticoid-free immunosuppression regimen. Islets are isolated by a collagenase-based digestion of donor pancreas with a "Ricordi" chamber, followed by a purification step in a Ficoll-based continuous density gradient. This review discusses the islet transplantation procedure and deals with the methods of islet isolation. Importance of islet preparations and engraftment quality, as well as clinical outcome and its indications also are described. The present status of islet regeneration including beta cells neogenesis and regeneration therapy strategies also are presented. The experience of Latvian scientists in islet transplantation procedure is briefly described.
