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 ...

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) ...

A new study reveals that vesicles packed with healthy mitochondria can supercharge tissue repair and combat chronic disease, paving the way for next-generation regenerative treatments. Study: ...

Whether you’re playing chess, playing center field or performing on stage, your body draws energy from tiny organelles within ...

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 ...

A muscle patch crafted from stem cells has improved cardiac function in monkeys with heart disease. It is now being tested in a small number of people, with early results from the first recipient ...

Cancer patients often lose excessive amounts of weight. This affects up to 80% of patients and is mainly due to a decrease in muscle mass and fatty tissue. This cancer-induced cachexia (CIC) is ...
