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 myoblasts (muscle stem cells) to proliferate. Unexpectedly, they found that PDGF-B also helps muscle fibers grow. They confirmed this corresponded to fibers contracting more strongly. Their findings promise game-changing therapies for treating muscular atrophy and injury.
