WebJan 1, 2024 · The ISCs in the small intestine reside at the bottom of the crypt and each crypt hosts 12–16 ISCs (Snippert et al., 2010 ). The ISCs are interspersed with a similar number of post-mitotic Paneth cells that collectively constitute a bowl-shaped stem cell compartment that occupies the crypt bottom. ISCs divide about once every 24 h. 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. diabetes and cinnamon blood sugar
