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 are protected by epithelial cells. This barrier tissue performs its function thanks to ...

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 ...

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

Cell adhesion is the process by which cells form contacts with each other or with their substratum through specialized protein complexes. Intercellular adhesion can be mediated by adherens ...

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

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 ...

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, ...

Plots of polarization-dependent efficiency of excitation could then be made, alongside the detection of emitted fluorescence. In trials using first labeled cellulose and actin targets and then cells ...

To further investigate the cell contribution to the ICM, the researchers labeled DNA and actin and, starting at the eight-cell stage, tracked cellular positions after division using live cell imaging.
