Crypts in biology
The intestinal glands in the colon are often referred to as colonic crypts. The epithelial inner surface of the colon is punctuated by invaginations, the colonic crypts. The colon crypts are shaped like microscopic thick-walled test tubes with a central hole down the length of the tube (the crypt lumen). Four tissue sections are shown here, two (A and B) cut across the long axes of the crypts … WebTypes of Biological Tests pH Test Cell Communication Apoptosis Autocrine Signaling Cell Junctions Cellular Response Changes in Signal Transduction Pathways Endocrine …

WebThe existence of crypt fusion in the human colon adds a new facet to our understanding of the highly dynamic and plastic phenotype of the colonic epithelium. We have provided the evidence that human colonic crypts undergo fusion, a potential homeostatic process to regulate total crypt number. WebCrypt cells of the small intestine provide stem cells for renewal of the intestinal epithelium, which turns over each 3 to 4 days. Xenobiotics that target rapidly dividing cells result in …

WebMay 14, 2009 · It is concluded that intestinal crypt villus units are self-organizing structures, which can be built from a single stem cell in the absence of a non-epithelial cellular niche. The intestinal epithelium is the most rapidly self-renewing tissue in adult mammals. We have recently demonstrated the presence of about six cycling Lgr5+ stem cells at the bottoms … WebAug 7, 2014 · Baker et al. examine the in vivo stem cell biology of human colonic crypts.

WebAug 23, 2016 · Colon and intestinal crypts serve as an important model system for adult stem cell proliferation and differentiation. We develop a spatial stochastic model to study the rate of somatic evolution in a normal crypt, focusing on the production of two-hit mutants that inactivate a tumor suppressor gene.
