A new single-nucleus atlas of mouse liver and skeletal muscle shows that individual cell types within these highly metabolic ...

Chick satellite cells from breast and leg muscles show opposite patterns of proliferation and differentiation when cultured ...

Sarcopenia, which is a progressive and extensive decline in muscle mass and strength, is common with aging and is estimated to affect up to 50% of people aged 80 and older. It can lead to disability ...

Building functional human muscle in the laboratory has long been a goal of regenerative medicine, but one stubborn obstacle remains: real muscle is not just a mass of cells. Its strength and function ...

UCLA researchers studying mice discovered that stem cells in aged muscle accumulate a protective protein called NDRG1 that slows their ability to repair tissue but helps the cells survive longer — ...

A research team has found that specific immune cells can connect with muscle fibers in a lightning-fast, neuron-like way to promote healing. These cells deliver quick pulses of calcium, triggering ...

A former athlete or gym regular steps away from training, the body softens, and someone inevitably says their muscle has "turned into fat." It's one of the most repeated fitness claims around, and it ...
