Scientists Create Insulin-Producing Beta Cells in a Dish

Postnatal maturation of pancreatic beta cells necessary for maximal glucosestimulated insulin secretion is coordinated by the estrogen-related receptor g (ERRg). ERRg drives a transcriptional program promoting mitochondrial oxidative metabolism, and its expression in iPSC-derived beta-like cells generates functional beta cells in vitro.

Generating functional pancreatic β (beta) cells in the lab has been a challenge for diabetes researchers. When human stem cells develop into beta cells in a dish, they only reach a precursor stage, unable to fully mature. Now an international team of scientists has discovered a nuclear receptor protein that activates the maturation process in vitro. Postnatal maturation of pancreatic beta cells necessary for maximal glucosestimulated insulin secretion...
