Biomedical engineers have developed a silk-based, ultrathin membrane that can be used in organ-on-a-chip models to better mimic the natural environment of cells and tissues within the body. When used ...

A new study answers the question of whether or not blood cell telomere length is a suitable proxy for telomere length in other tissues by examining over 20 human tissue types, finding variations and ...

Biologists have long treated cell membranes as passive barriers, thin skins that separate the chemistry of life from the ...

The epithelium is a type of tissue that covers many different surfaces on the inside and the outside of your body. Epithelial cells are packed tightly together and serve as a barrier between the ...

Acidification of intracellular compartments by the vacuolar-type H+-ATPases (VHA) is known to energize ion and metabolite transport, though cellular processes influenced by this activity are poorly ...

A septate uterus is when a thin tissue membrane, called the septum, runs down the middle of the uterus (womb) and divides it into two separate parts. This condition occurs when the baby is developing ...
