A UCLA study in mice reveals that aging muscle stem cells accumulate a protein that slows repair but boosts survival. This protein, NDRG1, acts like a brake, preventing cells from activating quickly ...

Researchers from the University of Southern Denmark investigated how eight weeks of high-intensity interval training affect the structure of mitochondria—the parts of muscle cells that produce energy.

Building functional human muscle in the laboratory has long been a goal of regenerative medicine, but one stubborn obstacle ...

Scientists at the University of California, Irvine's School of Pharmacy & Pharmaceutical Sciences have discovered how muscle ...

Muscle tissue from aged mice seven days after injury. Left: Aged mice with normal NDRG1 levels show slower regeneration with smaller muscle fibers. Right: Aged mice in which NDRG1 was recently blocked ...

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) ...

With modern scientific research, much of the old gym folklore has either been debunked or proven to be true. One example is the concept of muscle memory. The belief is that a seasoned trainee who ...

For a heart just damaged by a blocked artery, timing matters. So does access. That is what makes a new experimental treatment ...
