When Ashley Perlow felt a sharp pain shoot across her chest and into both wrists, she didn't think it could be a heart attack ...

Scientists have shown that a single injection of self-amplifying RNA, delivered into skeletal muscle rather than the heart ...

Study shows greater muscle area in men leads increased risk of heart disease; it's different for muscle density. Body composition -- often expressed as the amount of fat in relation to muscle -- is ...

Large, human cardiac-muscle patches created in the lab have been tested, for the first time, on large animals in a heart attack model. This clinically relevant approach showed that the patches ...

Researchers have shown that cardiac scar tissue (fibroblasts) can be directly reprogrammed to heart muscle cells (cardiomyocytes) in mice. By treating mice post-heart attack with a virus carrying ...

The muscular system works to control the movement of our body and internal organs. Muscle tissue contains something called muscle fibers. Muscle fibers consist of a single muscle cell. They help to ...
