Intestinal Epithelium Regeneration (IER)

Cellular Process, Tissue Regeneration, Homeostasis
01

Overview

Intestinal epithelium regeneration is the process by which the lining of the intestine is continuously renewed and repaired. This process is essential for maintaining gut health, nutrient absorption, and barrier function. It involves the proliferation and differentiation of intestinal stem cells (ISCs), the activation of reserve stem cells upon injury, and potentially the dedifferentiation of mature epithelial cells. Key signaling pathways such as Wnt/β-catenin and Notch regulate this process. Impaired regeneration contributes to various diseases, including IBD and cancer.
