The intestinal stem cell niche
WebThe intestinal stem cell niche consists of three zones along the crypt–villus axis: the crypt base columnar zone, the transit-amplifying zone, and the differentiation zone. The rapidly cycling intestinal stem cells are located at the base of the crypt, wedged between Paneth cells. In addition, dormant (reserve) intestinal stem cells reside in ...
