Regulation of the regeneration of intestinal stem cells after irradiation.

ABSTRACT:

Background

Radiation enteritis is common in cancer patients with abdominal and pelvic malignant tumors that have received radiotherapy. Regeneration of intestinal stem cells is a critical process for intestine self-repairing post-irradiation. In this study, we attempted to find out the molecules that promote the regeneration of intestinal stem cells to repair the irradiation damage.

Methods

Male C57BL/6 mice were given a single dose of 12 Gy irradiation, and in vitro cultured organoids were given 6 Gy X-rays to construct the regeneration of intestinal stem cells. Hematoxylin and eosin (H&E) staining was performed for morphological observation. In situ hybridization was used to detect the expression of Lgr5, and immunofluorescence staining was adopted to detect the exp
