Description

Description générale

The small intestine consists of continuous villi and crypts. The crypt is mainly a proliferative compartment and is maintained by multipotent stem cells whereas the villus represents the differentiated compartment, and it receives cells from multiple crypts. The functional compartment of the epithelium contains differentiated cells that populate the villi and can be categorized based on their function: enterocytes that function to absorb nutrients, goblet cells that secrete a protective mucus barrier, and enteroendocrine cells that release gastrointestinal hormones. Intestinal crypts contain intestinal stem cells (ISC), which are multipotent adult stem cells that reside in the base of crypts. They continuously self-renew by dividing and differentiate into the specialized cells of the intestinal epithelium, which renews throughout life. ISCs located either at the crypt base interspersed between the Paneth cells can be categorized into active-cycling (Lgr5+ cells) or those located near the þ4 position in the crypt as slow-cycling Bmi-1+ cells. Paneth cells that are responsible for secreting antibacterial peptides reside at the base of the proliferative compartment. As ISCs begin to differentiate, they migrate toward the lumen and are eventually shed, either from the tip of the intestinal villi or from the surface of the colonic epithelium. Villus represents the differentiated compartment of intestinal cells. Clone B6A6 recognizes most villous cells except goblet cells. (Ref.: Smith, NR., et al. (2018). Cell. Mol. Gastroenterol.

Spécificité

Clone B6A6 is a rat monoclonal antibody that detects intestinal villus cells.

Immunogène

Undifferentiated Mouse intestinal epithelial cells. Rats were preimmunized with isolations of differentiated mouse intestinal epithelial cells and then treated with cyclophosphamide (i.p.) to eliminate B lymphocytes reacting against these antigens. Subsequent immunization was with crypt-based single cells.
