Aging muscles heal more slowly after injury—a frustrating reality familiar to many older adults. A UCLA study conducted in mice reveals an unexpected cause: Stem cells in aged muscle accumulate higher ...

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 ...

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) ...

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 ...

Penn Medicine researchers unveiled in a recently published paper that a type of stem cell originating in skeletal muscle cells can turn into bone. Published in the Proceedings of the National Academy ...
