Adult stem cell
Videos
Adult stem cells are undifferentiated cells, found throughout the body after development, that multiply by cell division to replenish dying cells and regenerate damaged tissues. They are also known as

Intestinal gland

In histology, an intestinal gland is a gland found in between villi in the intestinal epithelial lining of the small intestine and large intestine. The glands and intestinal villi are covered by epith
Micrograph of the small intestine mucosa showing the intestinal glands - bottom 1/3 of image. H&E stain.
Colonic crypts (intestinal glands) within four tissue sections. In panel A, the bar shows 100 μm and allows an estimate of the frequency of crypts in the colonic epithelium. Panel B includes three crypts in cross-section, each with one segment deficient for CCOI expression and at least one crypt, on the right side, undergoing fission into two crypts. Panel C shows, on the left side, a crypt fissioning into two crypts. Panel D shows typical small clusters of two and three CCOI deficient crypts (the bar shows 50 μm). The images were made from original photomicrographs, but panels A, B and D were also included in an article
