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 ...

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, ...

Scientists use a multimodal approach that combines hard X-ray computed tomography and X-ray fluorescence imaging to see the structure and chemical processes inside of a single cell. Every plant, ...

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 ...
