Studying spaceflight atrophy with machine learning

Even intense exercise by astronauts cannot compensate for muscle atrophy caused by microgravity. Atrophy occurs, in part, by way of an underlying mechanism that regulates calcium uptake. Recent research has shown exposure ...

Scientists discover secreted protein helps repair and grow muscles

Scientists from Tokyo Metropolitan University have discovered that a protein called platelet-derived growth factor subunit B (PDGF-B) is continuously secreted from skeletal muscle cells and helps to repair muscles by encouraging ...

Mini but mighty: Tiny WNT messengers help muscles grow

WNT signaling is crucial for the development of organisms and the maintenance of tissue homeostasis, since the WNT messengers are involved in a variety of cellular functions. In skeletal muscle, for example, they can increase ...

An antioxidative stress regulator protects muscle tissue in space

Many kids dream of growing up to be astronauts; but the downside of spending extended amounts of time in low gravity is that astronauts' muscles tend to shrink and weaken through disuse. Now, researchers from Japan have identified ...

Researchers use silkworm silk to model muscle tissue

Researchers at Utah State University are using silkworm silk to grow skeletal muscle cells, improving on traditional methods of cell culture and hopefully leading to better treatments for muscle atrophy.
