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 ...

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 ...

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

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 ...

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 ...

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 ...

Side section of the skin with epidermal stem cells (green) with one particular clone in red. Cell nuclei are stained in blue, the white dashed lines indicate hair follicles. How does a normal cell in ...
