It has been suggested that new β cells can arise from specific populations of adult pancreatic progenitors or facultative stem cells. However, their existence remains controversial, and the conditions under which they would contribute to new β cell formation are not clear. Here, we use a suite of mouse models enabling dual recombinases-mediated genetic tracing to simultaneously fate map insulin+ and insulin− cells in the adult pancreas. We find that the insulin− cells, of both endocrine and exocrine origin, do not generate new β cells in the adult pancreas during homeostasis, pregnancy or injury, including partial pancreatectomy, pancreatic duct ligation or β cell ablation with streptozotocin. However, non-β cells can give rise to insulin+ cells after extreme genetic ablation of β cells, consistent with transdifferentiation. Together, our data indicate that pancreatic endocrine and exocrine progenitor cells do not contribute to new β cell formation in the adult mouse pancreas under physiological conditions.
