Lineage tracing evidence for in vitro dedifferentiation but rare proliferation of mouse pancreatic beta-cells.

abstract：:Islet transplantation is a promising treatment for type 1 diabetes. However, islet grafts are submitted to multiple injuries, including immunosuppressive drug toxicity, hyperglycemia, hypoxia, unspecific inflammatory reactions, as well as allo- and autoimmune destruction. Therapeutic approaches to these damage mechani...
