In the small intestine, epithelial cells are derived from stem cells in the crypts, migrate up the villus as they differentiate and are ultimately shed from the villus tips. This process of ...
The crypt–villus architecture of the intestinal mucosa is underpinned by dynamic interactions between distinct populations of epithelial, stromal and immune cells. Although the epithelial compartment ...
