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 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 ...

hello in this video we're going to talk about tissues a tissue is a group of similar cells and cell products that work together to perform a specific structural and physiological role in an organ ...

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

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 ...

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 ...

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 ...

Studies have demonstrated a critical role of the cytokines thymic stromal lymphopoietin (TSLP), IL-33, and IL-25, produced by epithelial and other cells at mucosal surfaces in response to a wide range ...
