Senescence is a process in which a cell ages and stops dividing but does not die. In keratinocytes, or skin cells, senescence is marked by depolarization of membrane potential (Vmem), the electrical ...

Cells manage a wide range of functions in their tiny package — growing, moving, housekeeping, and so on — and most of those functions require energy. But how do cells get this energy in the first ...

Billions of years of evolution have made modern cells incredibly complex. Inside cells are small compartments called organelles that perform specific functions essential for the cell’s survival and ...

Researchers have created a way to guide and control the development of stem cells into specific tissues and organs, opening the door to developing a means of one day tackling complex diseases like ...

All living organisms are made of cells, which are the smallest unit of life. Plants and animals have up to trillions of cells that work together to produce ever more intricate organization and ...

Scientists are learning how to revive faltering human cells by loading them with fresh power plants, effectively repairing ...

The most diverse functions of a cell in the human body – from cell division and differentiation to motility and programmed cell death – are controlled by signaling proteins within the cell. This ...

Until now, doctors knew hepatic stellate cells mainly as drivers of liver fibrosis. The actual functions of this cell type have hardly been studied to date. Researchers have now determined that ...

A novel 3D cell culture method has been developed that encourages liver progenitor cells to self-organize and form blood vessel networks for the first time. The development of accurate liver organoids ...

Scientists hoping to discover better ways to boost immune function — which could lengthen our healthspan and protect immunocompromised patients — may have a new target, according to findings published ...
