DNA … WebJul 13, 2001 · Above 8 grays (Gy), dose-dependent stem cell death leads to diminution of crypt regeneration, until the level of regeneration is insufficient to rescue the GI mucosa. In such cases, progressive denudation of the epithelium leads, by day 6 to 7 after radiation, to death of mice from the GI syndrome.

The crypts look like dimples in the gut lining and are vulnerable to damage and loss from infection and inflammation.

WebHome Page: Gastroenterology WebThis renewal process involves rapid and continuous proliferation of epithelial cells in the crypt base with subsequent migration of these cells along the crypt-villus axis. The process of epithelial cell renewal within the intestine appears to be entirely dependent upon a limited number of long-lived multipotent intestinal stem or progenitor cells.

WebSep 12, 2024 · Abstract Colonic wound repair is an orchestrated process, beginning with barrier re-establishment and followed by wound channel formation and crypt regeneration. Elevated levels of prostaglandin E2 (PGE2) promote barrier re-establishment; however, we found that persistently elevated PGE2 hinders subsequent repair phases.
