Brief summary: In this experimental study, genome editing and in vitro pancreatic differentiation of human pluripotent stem cells (SC) were used to generate ZNT8 loss-of-function (LOF) SC-β-cells. These cells showed accelerated functional maturation, increased insulin secretion and improved resistance to metabolic stress. Transplantation of ZnT8 LOF SC-β-cells into mice with preexisting diabetes significantly improved their glucose levels.<...
