Conner Curran, 9, (right) and his brother Will, 7, at their home in Ridgefield, Conn. The gene therapy treatment that stopped the muscle wasting of Conner's muscular dystrophy two years ago took more than 30 years of research to develop.

Gene therapy has helped a 9-year-old boy regain enough muscle strength to run. If successful in others, it could change the lives of thousands of children with Duchenne muscular dystrophy. NPR's Jon Hamilton tells us about Conner and his family...and one of the scientists who helped develop the treatment, a pioneer in the field of gene therapy.
