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 by epithelium that contains two types of cells: goblet cells that secrete mucus and enterocytes that secrete water and electrolytes.

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.
