ABSTRACT: PeyerM-bM-^@M-^Ys Patches consist of domains of specialized intestinal epithelium overlying Gut-Associated Lymphoid Tissue (GALT). Luminal antigens reach the GALT by translocation through epithelial gatekeeper cells, so-called M cells. We have recently demonstrated that all epithelial cells required for the digestive functions of the intestine are generated from Lgr5-expressing stem cells. Here, we show that M cells also derive from these crypt-based Lgr5 stem cells. The Ets family transcription factor Spi-B, known to control effector functions of bone marrow-derived immune cells, is specifically expressed in M cells. In Spi-B-/- mice, M cells are entirely absent, which occurs in a cell-autonomous fashion. It has been shown that Tnfsf11 (RankL) can induce M cell development in vivo. In int
