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. 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.
