Self-healing engineered muscle grown in the laboratory

Biomedical engineers have grown living skeletal muscle that looks a lot like the real thing. It contracts powerfully and rapidly, integrates into mice quickly, and for the first time, demonstrates the ability to heal itself ...

Damaged muscles don't just die, they regenerate themselves

A research collaboration between Kumamoto University and Nagasaki University in Japan has found that components leaking from broken muscle fibers activate "satellite" muscle stem cells. While attempting to identify the proteins ...

Strong change of course for muscle research

Anyone who climbs the 285 steps to the viewing platform of Berlin's Siegessäule, or Victory Column, will probably have quite a few sore muscles the next day. Out-of-the-ordinary activities such as climbing lots of steps ...

Scientists discover how satellite RNA leads to cancer

Only some of us have satellite TV in our homes, but all of us have satellite DNA in cells in our bodies. Working copies of satellite DNA (called satellite RNAs) are high in certain types of cancer, such as breast and ovarian. ...

Stem cell study may result in stronger muscles in old age

Muscular function declines with age. A new study by researchers at Karolinska Institutet in Sweden shows how an unexpectedly high number of mutations in the stem cells of muscles impair cell regeneration. This discovery may ...

Tumor suppressor key in maintaining stem cell status in muscle

A gene known to suppress tumor formation in a broad range of tissues plays a key role in keeping stem cells in muscles dormant until needed, a finding that may have implications for both human health and animal production, ...

Scientists speed up muscle repair—could fight dystrophy

Athletes, the elderly and those with degenerative muscle disease would all benefit from accelerated muscle repair. When skeletal muscles, those connected to the bone, are injured, muscle stem cells wake up from a dormant ...

Researchers isolate human muscle stem cells

UC San Francisco researchers have successfully isolated human muscle stem cells and shown that the cells could robustly replicate and repair damaged muscles when grafted onto an injured site. The laboratory finding paves ...
