Crypt feeder cells

WebCrypt cells of the small intestine provide stem cells for renewal of the intestinal epithelium, which turns over each 3 to 4 days. Xenobiotics that target rapidly dividing cells result in epithelial villus atrophy. Specific biomarkers for small intestinal mucosal injury are limited.

Wnt ligands, produced by both Paneth and surrounding stromal cells, bind to their cognate receptors Frizzled (FZD) and low-density lipoprotein receptor-related protein 5/6 (Lrp5/6) at the surface of adjacent stem cells. WebEpithelial cells are continuously renewed every 4–5 days through a process of cell division, maturation, and migration.
