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

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 created protein fibers inspired by various animal muscle proteins. These materials are grown in bioreactors and can be stronger than many synthetic fibers.

Supplementing a single protein found in the spinal cord could help prevent symptoms of Lou Gehrig's disease, according to a new study. Researchers found high levels of the protein -- called mitofusion ...

Engineers at Washington University in St. Louis have developed a new class of protein-based fibers modeled on the aligned ...

Diagnosing a muscular disorder, disease or infection often requires a sample of the tissue to be extracted, but these biopsies can be painful and difficult to perform. Researchers at the ...

As people age, muscles naturally lose mass and strength, a condition known as sarcopenia. The decline can make everyday activities harder and increases the risk of falls, disability and early death.

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, ...

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 ...

Fast-twitch fibers help with explosive movements like sprinting and weight lifting. Genetics and training influence the distribution of fast-twitch and slow-twitch muscle fibers. Doing strength ...
