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.
