Crypts colon
WebThere are crypts that are elongated but straight, narrow and hyperchromatic at the base. All crypts reach to the muscularis mucosae. [4] The basement membrane is frequently thickened. [4] Goblet cell-rich type [ edit] Elongated, fat crypts and little to no serration. 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.

WebIn this regard, it is interesting that genetic analysis of early-stage human colon tumors, specifically excluding tumors in FAP patients, suggested that human sporadic colon tumors may form in a top-down manner, with transformed cells and dysplastic crypts farther up along the crypt–luminal axis expanding down into the crypt . Thus, although ...
