These cells are found in the crypts of Lieberkühn - deeply invaginated sections of the colon's mucosal layer. The prime function of intestinal crypt stem cells of the colon is to serve as the source of constant cell regeneration in the colon. Every few days, these stem cells divide and differentiate into the various other types of intestinal cells, such as enterocytes, goblet cells, and enteroendocrine cells. A constant renewal cycle is necessary due to the harsh environment of the colon where cells continuously encounter abrasive food matter and potential pathogens, leading to a high turnover rate. When the colon's mucosal layer suffers damage, a rapid response is triggered whereby colon crypt stem cells divide faster and are directed to injured sites to repair the epithelial layer. Dysregulation of these cells' function or proliferation can contribute to disorders such as colorectal cancer.
