Crypt fission
WebSep 2, 2024 · Fission of a stem cell crypt into two or more daughter stem cell zones (SCZs) is a key driver of intestinal elongation during development and infancy (Dudhwala et al., … WebMar 14, 2024 · Expansion of somatic mutations within the human colonic epithelium occurs through crypt fission, the process by which a parental crypt divides and produces two daughter crypts. Fission occurs at a low rate in the healthy adult colon; however, it is more frequent in certain disease states.

WebCrypt fission is now established as an important mechanism of intestinal growth and regeneration. It has been proposed that increased crypt size is the stimulus for crypt fission, because crypts preparing for fission are generally larger.
WebMar 19, 2024 · Crypt fission is responsible for the spread of mutations in the early stages of colorectal tumourigenesis, and also for the regeneration of the colonic epithelium after injury. Consequently, manipulating the balance of crypt fission and fusion may represent a novel strategy for the prevention of the early expansion of precancerous mutant clones WebMorphological characteristics and cellularproliferation were investigated in the hindgut tissue of25 pigs ranging from 5 to 261 days of age; the threeyoungest pigs were unweaned. Tissue samples were taken from the cecum and from the proximal,middle, and distal part of the colon. In the young pigsa high incidence of branched crypts was observed. Duringthe …
