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 ...

Most if not all organs in mammals have adult stem cells that have some capacity to make and repair tissues throughout the lifetime of the organism. To understand how stem cells achieve these functions ...

When a wound on the skin creates a gap, the epithelial cells of the skin, surrounding the wound, move in a concerted fashion to close this gap. The boundaries of these gaps can have different ...

Although epithelial folding is commonly studied using in vivo animal models, such models exhibit critical limitations in terms of real-time observation and independent control of experimental ...

Northwestern Medicine scientists have discovered a previously unknown process used by epithelial cells to alleviate epithelial tissue crowding and avoid cell damage and loss, according to a recent ...

A distinct signaling pathway called TNF- drives the transformation of epithelial cells into aggressive tumor cells. During cancer progression, cells activate their own TNF- program and become invasive ...
