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 ...

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, ...

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 at the School of Medicine at the University of California, Riverside have discovered previously unrecognized ...

Neurons talk to one another using electricity. If you could hear these impulses, they might sound like constant, rapid-fire chatter all over the nervous system. Heart muscle cells do something similar ...

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 ...
