Researchers building a model of muscle damage in a cultured system found that components leaking from broken muscle fibers activate ''satellite cells,'' which are muscle stem cells. While attempting ...

Researchers are using silkworm silk to grow skeletal muscle cells, improving on traditional methods of cell culture and hopefully leading to better treatments for muscle atrophy. Researchers at Utah ...

Hidden inside every organ, microscopic fibers form a scaffolding that quietly shapes how we move, think, and heal. For the ...

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 ...

For decades, scientists believed that muscle fiber typology was mostly set at birth—some people were built for speed, others for endurance. However, a 2018 study led by Andrew Galpin of California ...

slow-twitch muscle fibers, which move more slowly but help to keep you moving longer fast-twitch muscle fibers, which help you move faster, but for shorter periods “Twitch” refers to the contraction, ...
