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 ...

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 ...

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 ...

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 ...

Biological muscles act as flexible actuators, generating force naturally and with an impressive range of motion. Unsurprisingly, scientists and engineers have been striving to build artificial muscles ...

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 ...

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 ...
