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. WebNov 15, 2024 · Samuelson and colleagues demonstrate that activation of CreERT2 in the mouse intestine leads to intestinal stem cell (ISC) toxicity. Impaired stem cell function was shown by reduced organoid-forming ability in ISC-CreERT2 strains. Also, Villin-CreERT2 mice exhibited impaired crypt regeneration after ISC injury induced by γ-irradiation. DNA …
