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 have identified the role of the large Maf transcription factor family in regulating fast twitch muscle fibers. A mouse model lacking Maf expression in the skeletal muscles exhibited a ...

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 ...

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 ...

The mechanism of skeletal muscle contraction is a process that relies on calcium signaling. However, the physiological role of calcium-induced calcium release (CICR) through the ryanodine receptor ...

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, ...

While building a muscle damage model in a cultured system, a research collaboration between Kumamoto University and Nagasaki University in Japan has found that components leaking from broken muscle ...
