Crypt regeneration

WebEstablished crypt abscesses are rare. The changes are commonly patchy, and the overall mucosal architecture is preserved. Minimal degenerative changes, limited to the upper half of the mucosa, can be seen. These include mucin depletion and epithelial damage with flattened cytoplasm associated with cryptic dilatation. 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.
