WebSTING is required for intestinal regeneration after radiation injury Crypt regeneration after 15 Gy TBI is characterized by highly enlarged crypts at 96 hours (more than 200% increase in size) driven by the rapid proliferation of single surviving clonogenic cells following the loss of existing crypts between 48 and 72 hours (Fig. 1A and fig. S1A). 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.

WebJul 14, 2024 · Introduction. As one of the most rapidly renewing tissues, the intestine has a great capacity for regeneration. Under homeostatic conditions, Lgr5+ crypt base columnar stem cells (CBCs) are responsible for replenishing the intestinal epithelium throughout life (Barker et al., 2007).This intestinal stem cell (ISC) population generates highly … WebSep 25, 2024 · Regeneration requires stromal Rspo3, which is present at increased levels upon injury and reprograms Lgr5 - but Lgr4 + differentiated cells. In contrast, depletion of stromal Rspo3 impairs crypt regeneration, even upon mild injury. We demonstrate that Rspo3 is essential for epithelial repair via induction of Wnt signaling in differentiated cells.

Elevated levels of prostaglandin E2 (PGE2) promote barrier re-establishment; however, we found that persistently elevated PGE2 hinders subsequent repair phases.

WebMay 20, 2024 · These diverse requirements led to the evolution of crypt and villus domains, which support regeneration and nutrient uptake respectively. Within each domain, we find even more refined zonation with certain cell types and functions appearing only in specific positions along this crypt-villus axis.

WebBased on those findings we opted for classifying crypts with regenerative, 'indefinite for dysplasia' or low-grade dysplasia [24] as with inconclusive or suspected cellular changes (ISCC), and those with HGD (the histological phenotype less amenable to diagnostic disagreement) [25].
