Group 3 innate lymphoid cells amplify YAP1-driven small intestinal repair

Ror gamma t-deficient mice lack group 3 Innate Lymphoid Cells (ILC3s) and as a result have increased tissue damage and diminished tissue repair in response to insult. To identify repair programs associated with ILC3 presence the transcriptomes of small intestinal stem cells exposed to damage in the presence or absence of ILC3 were compared. Small intestinal damage was induced in Ror gamma t-deficient Lgr5 reporter mice and littermate controls. Small intestinal epithelial stem cells were purified at days 1 and 4 after damage and subjected to RNA sequencing.
