Crypt-base columnar cells

WebThe villous epithelium of the intestines is regenerated by Lgr5 + stem cells (ISCs) called crypt base columnar cells (CBCs) that reside within the bottom three cells of the crypts of Lieberkuhn and are interspersed with Paneth cells, which are derived from the ISCs. A molecular marker specific to ISCs up to position 7 is the Lgr4 protein.

WebThe crypt epithelium consists Paneth cells, crypt base columnar cells, oligomucous cells and a few granulated enteroendocrine cells. WebThey give rise to short-term Lgr5 + cells residing at the crypt base, also known as crypt base columnar cells (CBCs), which are interspersed between the Paneth cells. The Lgr5 + ISCs are active cells that contribute robustly to homeostatic regeneration, and are quantitatively ablated by irradiation. WebIn the present work, direct evidence was obtained in support of this view. It was first found that crypt-base columnar cells phagocytose non-viable cells in their vicinity, with the result that a large phagosome appears in the cytoplasm. Such phagosomes were then used as markers to follow the evolution of crypt-base columnar cells. hiko twitch stats
