WebSep 20, 2005 · proliferation of mouse embryo fibroblasts (MEFs) in vitro. Here, to investigate the in vivo relevance of these findings, we evaluated the turnover rates of small intestine crypt stem cells from WT and Cav-1 deficient mice. Interestingly, we show that Cav-1 null crypt stem cells display higher proliferation rates, as judged by BrdU and PCNA ... WebProliferative rate is the more biologically relevant measurement but its assessment requires either systemic administration of cytotoxic drugs or in vitro incubation of tissue—the former is not applicable in human subjects and the latter is subject to artefacts introduced by removal of the tissue from in vivo homeostatic influences.
Buried Barrett
WebPost-PDT buried BE showed a significantly lower Ki-67 crypt proliferation rate (29.9%) in comparison to nonburied BE, in both pre- PDT (43.3%) and post-PDT (44.4%) biopsies (P < 0.05), but similar rates of positivity for the other peptide markers. In contrast to pre-PDT nonburied BE biopsies, high fidelity DNA histograms revealed that none of ... WebRESULTS In the small intestine, EGF significantly increased epithelial cell proliferation and crypt and villus area after 24 hours of EGF, although maximal effects were only reached following six days of infusion. EGF also resulted in an approximate 30% reduction in crypt fission in the small bowel. In the colon, EGF caused a twofold increase in epithelial cell … crystal flash marshall michigan
