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 ...

Cells can also send out packages called exosomes, lipid vesicles that bubble off from the cell membrane. But for about 20 ...

Northwestern Medicine investigators have uncovered new insights into how intercellular "glue" functions to enable ...

The actin cytoskeleton provides force for dynamic cellular processes, such as motility, morphogenesis, cell division, endocytosis, and phagocytosis. The organization and dynamics of actin filaments ...

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 ...

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 ...

Who were our earliest ancestors? The answer could lie in a special group of single-celled organisms with a cytoskeleton similar to that of complex organisms, such as animals and plants.

postdoc Yee Han Tee had begun working with another sort of micropatterning technique to study how cells form an internal structure called the actin cytoskeleton, an important mediator of cell growth, ...
