Human induced pluripotent Endothelin Receptor stem cells (HiPSCs) appear to be extremely similar to human embryonic stem cells (HESCs). Applying two genetic lineage-tracing systems, we show the generation of iPSC lines from human pancreatic islet beta cells. These reprogrammed cells acquired selleck chem inhibitor markers of pluripotent cells and differentiated into the 3 embryonic germ layers. However, the beta cell-derived iPSCs (BiPSCs) maintained open chromatin structure at important beta-cell genes, together with a exclusive DNA methylation signature that distinguishes them from other PSCs. BiPSCs also demonstrated an increased capability to differentiate into insulin-producing cells each in vitro and in vivo, compared with ESCs and isogenic non-beta iPSCs. Our results recommend that the epigenetic memory might predispose BiPSCs to differentiate a lot more readily into insulin generating cells. These findings demonstrate that HiPSC phenotype might be influenced by their cells of origin, and suggest that their skewed differentiation probable might be beneficial for www.selleckchem.com/products/MDV3100.html cell substitute therapy.
