In such cases, progressive denudation of the epithelium leads, by day 6 to 7 after radiation, to death of mice from the GI syndrome.
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.
