Fecal Microbiota Transplantation From Young Mice to Old Mice Improves Intestinal Stem Cell Function

A recent study demonstrates that transferring fecal microbiota from young to old mice restores intestinal stem cell (ISC) function by reactivating canonical Wnt signaling. The young‑derived microbiota increased expression of Ascl2 and Lgr5, boosted crypt mitotic activity, and improved regenerative capacity in aged intestines. Conversely, transplanting aged microbiota into young mice had minimal impact, highlighting age‑specific responsiveness. The findings suggest microbiome modulation could rejuvenate the aging gut.
