Intestinal glands are found in the epithelia of the small intestine, namely the duodenum, jejunum, and ileum, and in the large intestine (colon), where they are sometimes called colonic crypts. Intestinal glands of the small intestine contain a base of replicating stem cells, Paneth cells of the innate immune system, and goblet cells, which produce mucus. In the colon, crypts do not have Paneth cells. WebSep 23, 2024 · However, drift is also a powerful evolutionary force, especially within small populations like intestinal crypts, where competition occurs between very limited numbers of neighboring stem cells 16.
