TL;DR: Comprehensive microRNA profiling in all major cell types of the mouse SI epithelium revealed highly enriched microRNA markers for almost every major cell type, and observed that the two most-enriched microRNAs in secretory progenitors are miR-1224 andMiR-672, the latter of which is deleted in hominin species.

In this study, first, microRNA atlas (and searchable web server) across all major small intestinal epithelial cell types is presented. We have demonstrated microRNAs that uniquely mark several lineages, including enteroendocrine and tuft. Identification of a key marker of mouse secretory progenitor cells, miR-672, which we show is deleted in humans. We have used several in vivo models to establish miR-152 as a specific marker of Paneth cells, which are highly understudied in terms of microRNAs.
