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

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 ...

Scientists reveal the role of hidden microbes called Asgard archaea in the origins of complex life, challenging long-held ...

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 ...

ETH researchers discovered related structures in Asgard archaea and describe their structure. These experiments show that ...

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 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, ...

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.
