A new 3D model shows that Duchenne gene therapy can repair muscle fibers but fails to shut down the signals that drive scarring.

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 ...

Engineers at Washington University in St. Louis have developed a new class of protein-based fibers modeled on the aligned structure of animal skeletal muscle, producing materials that resist ...

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.

No matter how regularly you exercise, artificial muscles have long since surpassed their natural counterparts. Now, researchers from the Department of Mechanical Science and Engineering at the ...

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 ...

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, ...

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.

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 ...
