Colonic crypts (intestinal glands) within four tissue sections. In panel A, the bar shows 100 μm and allows an estimate of the frequency of crypts in the colonic epithelium. Panel B includes three crypts in cross-section, each with one segment deficient for CCOI expression and at least one crypt, on the right side, undergoing fission into two ...
Crypts are anatomical structures that are narrow but deep invaginations into a larger structure. One common type of anatomical crypt is the Crypts of Lieberkühn. [1] However, it is not the only type: some types of tonsils also have crypts. Because these crypts allow external access to the deep portions of the tonsils, these tonsils are more ...

Nooteboom et al. [33] measuring the number of cells in a small number of crypts reported a range of 1,500 to 4,900 cells per colonic crypt. Cells are produced at the crypt base and migrate upward along the crypt axis before being shed into the colonic lumen days later. [32] There are 5 to 6 stem cells at the bases of the crypts. [32]
