Epithelial cells line the body’s surfaces to protect against physical damage, pathogens, and dehydration. These cells play key roles in absorbing nutrients and removing waste products, as well as ...

Deep in the folds of the intestine, in microscopic pockets called crypts, a quiet surveillance system is always at work. Stem ...

Epithelial cells cover the surfaces of most organs in the body and must adhere to each other to form both a protective and permeable barrier. They are exquisitely designed to both be tightly sealed ...

Researchers have resolved a 50-year-old scientific mystery by identifying the molecular mechanism that allows tissues to ...

The intestinal epithelium undergoes rapid renewal every 3–5 days, a process driven by intestinal stem cells (ISCs) located at the base of crypts.

Cranberry extract may strengthen intestinal barrier function via microbiota-dependent and direct epithelial effects.

The discovery that tissues use electricity to expel unhealthy cells is part of a surge of renewed interest in the currents flowing through our bodies. We’re used to thinking of the brain as an ...
