Between the villi are intestinal glands (crypts of Lieberkuhn) which secrete intestinal juice rich in digestive enzymes. Microvilli are projections found on the apical surface of each intestinal cell (enterocyte)

Crypt hyperplasia is when the grooves …
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. The enterocytes in the small intestinal mucosa contain digestive enzymes that digest specific foods while they are being absorbed through the epithelium. These enzymes include peptidase, sucrase, maltase, lactase and intestinal lipase. This is in contrast to the gastric glands of the stomach where chief cells secrete pepsinogen. Also, new epithelium is formed here, which is important because the cells at this site are continu…
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. WebThe crypts of Lieberkühn are straight and unbranched and lined largely with goblet cells. In many regions the mucus is partially preserved and stains with hematoxylin. At the base of the crypts, undifferentiated cells and …
WebCrypts (of Lieberkuhn) are moat-like invaginations of the epithelium around the villi, and are lined largely with younger epithelial cells which are involved primarily in secretion. …
