NIH scientists identify gene that could hold the key to muscle repair – 2
Narrator: This is NIH Health Matters. I’m Joe Balintfy. The process which enables the body to repair damaged muscle, works quite well. But Dr. Vittorio Sartorelli, a senior investigator at NIH says muscles will deteriorate because of injury or age.
Sartorelli: Because of the mechanical properties of the muscle every time that there is contraction there is some sort of wear and tear effect.
Narrator: Now researchers are studying the roll of specialized cells called satellite cells, and a particular gene that affects satellite cell growth. Scientists found that when they turned off a specific gene in satellite cells, muscle damage caused by injury was not repaired. For more information on this research, visit www.niams.nih.gov.
