Building muscles: Muscle stem cells (their nuclei marked in blue) gradually alter their structure and function, becoming adult muscle cells (whose nuclei turn red). Those cells will eventually fuse ...

Aging muscles heal more slowly after injury - a frustrating reality familiar to many older adults. A new UCLA study conducted ...

Johns Hopkins University biologists have found that a protein that plays a key role in the lives of stem cells can bolster the growth of damaged muscle tissue, a step that could potentially contribute ...

In work published in Nature Biotechnology, Rubin and his research group turned to 3D cell culture to take on the problem of generating sufficient satellite cells for regenerative therapies. 2 ...

Thirty marks the spot. Starting at this age, we begin to lose approximately three to eight percent of muscle mass per decade. With it, we also lose strength and mobility. Left unaddressed, this loss ...

Stem cells that live in the muscle impart its ability to regenerate. After an injury, muscle stem cells activate and must expand in number to repair and make new muscle (marked by dystrophin in white) ...

Working out doesn't just build muscle but, in later life, helps maintain a powerful cellular machine that repairs damaged ...
