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 ...
Claudin family tight junction proteins form charge- and size-selective paracellular channels that regulate epithelial barrier function. In the gastrointestinal tract, barrier heterogeneity is ...
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 short regulatory peptide known as Bronchogen is attracting growing attention among researchers for its proposed role in ...
Researchers have discovered a new way that epithelial cells, which form layers in organs like the skin and stomach, attach to one another, and how they perceive growth signals at these attachments, ...
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 ...
In vitro modeling of small airway epithelium for studying barrier function and mucociliary clearance
The small airways serve as a primary line of defense against inhaled particles and facilitate gas exchange by directing air to the alveoli. These small airways are critical in the pathophysiology of ...
A research team led by scientists from the State University of Campinas (UNICAMP) in São Paulo, Brazil, has made significant progress in understanding the relationship between gut microbiota and ...
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 ...
