Our skin and mucous membranes are protected by epithelial cells. This 'barrier' tissue performs its function thanks to specialized structures called 'junctions'. They ensure cell cohesion and regulate ...

Epithelial cells defend human skin and mucous membranes. Specialized structures known as “junctions” enable this “barrier” tissue to carry out its role. They control interactions between cells and ...

Researchers will soon be able to study biological changes at scales and speeds not previously possible to significantly ...

Just as cities must carefully manage the flow of cars in and out of downtown, cells regulate the movement of molecules into ...

Our skin and mucous membranes protect us like vigilant sentinels against the onslaught of harmful pathogens. This extraordinary defense owes its strength to epithelial cells—specialized tissues woven ...
