WebApr 28, 2024 · In 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. WebThe crypts of Lieberkuhn (often referred to simply as crypts) are similar to the gastric pits in the stomach. The crypts contain stem cells that can produce a number of different cell types, including enterocytes 2. From …

WebFeb 26, 2024 · Two stem cell states have been identified within the crypts of the small intestine: ‘quiescent’ and ‘active’. SOX9, a transcription factor encoded from the Sox9 gene has been hypothesized to be the master regulator between these ‘active’ (low expression of SOX9) and ‘reserve’ (high expression of SOX9) intestinal stem cell states. WebIntroduction. Inflammatory bowel disease (IBD) is a chronic, relapsing disease of the gastrointestinal (GI) tract, with frequent onset during adolescence or early adulthood. IBD is characterized by chronic activation of the immune system with inflammation of the intestinal tract and leakage of fluid, solutes, and lipids in the bowel mucosa.
