Our skin and mucous membranes are protected by epithelial cells. This barrier tissue performs its function thanks to ...

For example, humans alone have over 20 different kinds of integrins. Integrins link the actin cytoskeleton of a cell to various external structures. The cytoplasmic portion of each integrin ...

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 ...

In nondividing cells, microtubule networks radiate out from the centrosome to provide the basic organization of the cytoplasm, including the positioning of organelles. The protein actin is ...

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

Who were our earliest ancestors? The answer could lie in a special group of single-celled organisms with a cytoskeleton ...

A previously unknown protein in a family of bacteria found in soil and the human gut microbiome has been discovered—which ...

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 ...

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.
