As a highly regenerative organ, the intestine is a promising source for cellular reprogramming to replace lost pancreatic β-cells in diabetes. Gut enterochromaffin cells can be converted to insulin-producing cells by FoxO1 ablation, but their numbers are limited. In this study we report that insulin-immunoreactive cells with Paneth/goblet cell features are present in human fetal intestine. Accordingly, lineage tracing experiments show that upon genetic or pharmacologic FoxO1 ablation the Paneth/goblet lineage can also undergo conversion to the insulin lineage...
