Intestinal Enteroendocrine Lineage Cells Possess Homeostatic and Injury-Inducible Stem Cell Activity

Multiple cell populations, represented by distinct markers including Lgr5 and Bmi1, are capable of reconstituting the intestinal epithelium. Using comparative RNA-sequencing and single-cell transcriptomics, Yan et al. define Bmi1-GFP+ and Prox1+ cells as enteroendocrine lineage cells that possess intestinal stem cell activity during homeostasis and injury-induced regeneration.
