The layer of cells coating the gut — called the intestinal epithelium — is sloughed off and renewed about every three to five days. This regeneration is generally believed to be directed by ...

Salmonella bacteria invade and destroy the cells that line the intestine, known as the intestinal epithelium. This makes it harder for your intestine to absorb water and digest food properly. As a ...

During pregnancy, the breasts expand, resting heart rate speeds up, and organs shift to accommodate the growing fetus. And now, scientists have added one more item to this list: the gut grows ...

Barrett's esophagus is an acquired metaplastic abnormality in which the normal stratified squamous epithelium lining of the esophagus is replaced by an intestinal-like columnar epithelium.

Intestinal stem cells are multipotent adult stem cells, which in mammals reside in the base of the crypts of the adult intestine. Intestinal stem cells continuously self-renew by dividing and ...

The mechanical barrier is made up of the mucus layer, intestinal epithelial cells, tight junctions between cells and the mucosal lamina propria.

Cell competition in epithelial tissue eliminates transformed cells expressing activated oncoproteins to maintain epithelial homeostasis. Although the process is now understood to be of mechanochemical ...

The stem cells are propagated in vitro and form mature intestinal epithelium upon growth factor manipulation. In order to increase the complexity of this human biomimetic model, we are integrating ...
