Abstract
Peyer’s 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, the so-calledMcells. We recently demonstrated
that all epithelial cells required for the digestive functions of the intestine are generated from Lgr5-expressing stem cells.
Here, we show thatMcells also
