The epithelium is a type of tissue that covers many different surfaces on the inside and the outside of your body. Epithelial cells are packed tightly together and serve as a barrier between the ...

Epithelial stem cells play a central role in tissue homeostasis, wound repair, and carcinogenesis. Corneal epithelial stem cells have been demonstrated to reside in the limbal epithelium, while the ...

In recent years, many labs have focused on the identification and characterization of stem cells in various embryonic and adult tissues. These efforts have led to important discoveries about the ...

Epithelial tissues are in constant interaction with their environment. Maintaining their functionality requires dynamic balance (homeostasis) and that their cell numbers are tightly regulated. This is ...

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 ...

It has long been thought that only nerve and heart cells use electric impulses to communicate, while epithelial cells -- which compose the linings of our skin, organs and body cavities -- are mute, ...

Epithelial cells line various surfaces of the body, including the skin, blood vessels, organs, and urinary tract. A raised amount of epithelial cells in a person’s urine may indicate an underlying ...

Are prematurely aged or overworked stem cells a significant factor in chronic lung disease? Findings of a study just released in STEM CELLS Translational Medicine (SCTM) say this is likely so. The ...

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 ...
