Crypt small intestine
WebHowever, we demonstrate that the crypt fission index, or the incidence of crypts in fission, is some four times higher in the colon than in the small intestine at the time of ethyl nitrosourea injection, and propose an alternative hypothesis based on crypt fission as the mechanism for the more rapid evolution of wholly mutated crypts in the colon. WebAbstract. In the face of mechanical, chemical, microbial, and immunologic pressure, intestinal homeostasis is maintained through balanced cellular turnover, proliferation, differentiation, and self-renewal. Here, we present evidence supporting the role of the aryl hydrocarbon receptor (AHR) in the adaptive reprogramming of small intestinal gene ...

WebAug 12, 2024 · In the small intestine, the epithelium comprises repeating crypt-villus units, 5–positive (Lgr5+) crypt base columnar (CBC) stem cells located in the crypt base with lysozyme-secreting Paneth cells (PCs) forming a mosaic pattern [ 2] (Fig. 1 ). The close interaction of CBCs with PCs is essential to maintain the stem cell function of CBCs. Fig. 1
