The mechanism of intestinal stem cells differentiation after ischemia–reperfusion injury in a rat model

This rat model study demonstrates that intestinal ischemia-reperfusion injury shifts stem cell differentiation toward secretory cells rather than absorptive enterocytes at 48 hours post-injury. The findings reveal inhibited Wnt/β-catenin signaling and activated Notch pathways, suggesting critical pathway crosstalk that may inform therapeutic strategies for intestinal injury recovery.
