Crypt of intestine
WebIn histology, an intestinal crypt—called the crypt of Lieberkühn—is a gland found in the epithelial lining of the small intestine and colon. The crypts and intestinal villi are covered … WebThe intestinal epithelium is the single cell layer that form the luminal surface (lining) of both the small and large intestine (colon) of the gastrointestinal tract. Composed of simple columnar epithelial cells, it serves two main functions: absorbing useful substances into the body and restricting the entry of harmful substances.

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 … WebIn the intestine, crypts may also become more crowded with increased mitotic activity. However, these are subjective assessments and comparison to properly matched controls is important. PGE2 is protective during this process by supporting proliferation and reepithelialization, which further explains the destructive effects of COX inhibitors.
