Epithelial tissues form selective barriers and undergo complex remodelling throughout embryogenesis and organogenesis. Central to these processes are specialised intercellular junctions—tight ...

The intestinal epithelial barrier comprises a single layer of specialised cells connected by tight junctions, which regulate the passage of nutrients, ions and water while preventing the entry of ...

Scientists at Université de Montréal's Institute for Research in Immunology and Cancer (IRIC) have identified a dynamic structure that forms a network on the surface of epithelial cells. Led by ...

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 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 ...
