Genetic lineage tracing identifies adaptive mechanisms of pancreatic islet β cells in various mouse models of diabetes with distinct age of initiation

This study uses genetic lineage tracing to investigate the adaptive mechanisms of pancreatic islet β cells in various mouse models of diabetes. The results show that β-cells expand through self-replication and rarely trans-differentiate into α or δ cells in young mice, but recover β-cell identity after remarkable dedifferentiation in o...
