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 ...

Electron microscopy is a powerful technique that provides high-resolution images by focusing a beam of electrons to reveal fine structural details in biological and material specimens. 2 Because ...

Scientists have uncovered details of the protective layer that surrounds the fine protrusions of cells. Biological cells often possess thin, hair-like protrusions on their surface known as cilia, ...

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 ...

Cellular senescence is commonly defined as a state characterized by permanent cell cycle arrest in the absence of cell death, in which cells have altered function. While cellular senescence has been ...

When oil is dropped in water, the oil droplets stay separate. Cells can also use a system like this to separate or gather materials, encouraging various reactions and processes to occur. Scientists ...

Biomedical research typically follows a familiar path: developing treatments that block, enhance or mutate certain signaling pathways, genes or proteins to change the function of different cells in ...
