In vitro differentiation of human pluripotent stem cells (hPSCs) into different cell types of the pancreas. Overview of the stages of in vitro differentiation into the different pancreatic cell types, namely alpha, beta, acinar, and ductal cells. Beta cell differentiation protocols produce some monohormonal insulin+ cells that are glucose-responsive (beta-like cells) as well as nonfunctional insulin+ cells coexpressing other pancreatic hormones (polyhormonal cells). Upon implantation into mice, hPSC-derived pancreatic progenitors differentiate into glucose-responsive, insulin-secreting beta cells, as well as other endocrine cell types.
