Crypt proliferation
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 ... WebOct 6, 2024 · Crypt regeneration after 15 Gy TBI is characterized by highly enlarged crypts at 96 hours (more than 200% increase in size) driven by the rapid proliferation of single surviving clonogenic cells following the loss of existing crypts between 48 and 72 hours ( Fig. 1A and fig. S1A).

WebTo test whether it is possible to distinguish the two categories of ROS that affect crypt proliferation in vivo, we examined the consequences of deletion of Rac1 and TIGAR. The RAC1 GTPase has been shown to play an important role in controlling cell proliferation and is activated in several human cancers ( Sanz-Moreno et al. 2008 ; Krauthammer ... WebCrypt. (Science: pathology) deep pit that protrudes down into the connective tissue surrounding the small intestine. The epithelium at the base of the crypt is the site of stem cell proliferation and the differentiated cells move upwards and are shed 3-5 days later at the tips of the villi. What are the crypts?
