WebSep 12, 2013 · The LI studies revealed a distinct ordering along the crypt among proliferative cells at the crypt base and mature cells at the crypt orifice, an observation confirmed by more recent Ki67 immunostaining (a marker for cell proliferation) [10], [11]. WebJun 13, 2013 · The rate of cellular movement in the crypt column. A: The left panel shows the distribution of the number of mitoses needed to push a cell at position i out of the crypt column for each proliferation curve. Colors match the corresponding proliferation curves in Fig. 1C. The horizontal axis represents the position of the cell in the crypt.
WebJul 28, 2024 · To assess the effects of proliferation inhibition on crypt/villus migration, migrating and proliferating epithelial cells were monitored by double labelling with two thymine analogues (BrdU and IdU), administered sequentially a number of hours apart and subsequently distinguished by specific immunostaining in longitudinal sections of small … WebJun 7, 2024 · The intestinal crypt is the proliferative compartment of the epithelium, composed of intestinal stem cells and rapidly dividing transit amplifying cells [ 45 ]. As such, disruption of the cell cycle or cellular division in the crypt compartment has significant consequences for the entirety of the intestinal epithelium.
