Injecting Wnt7a protein could prevent Duchenne muscular dystrophy

Injecting Wnt7a protein could prevent Duchenne muscular dystrophy: Scientists have discovered that injecting a novel human protein into muscle affected by Duchenne muscular dystrophy significantly increases its size and strength, findings that could lead to a therapy akin to the use of insulin by diabetics. These results were published today in the Proceedings of the National Academy of Sciences by Dr. Julia von Maltzahn and Dr. Michael Rudnicki, the Ottawa scientist who discovered muscle stem cells in adults.
