For Diane Souza, working on her 23 acre ranch in Northern California is a labor of love. But an accident in 2011 left her with a broken arm that would not heal. Souza was faced with the possibility of having only one working arm. Not wanting to give up her ranch life, she entered a clinical trial that delivered bone marrow derived mesenchymal stem cells to her bone fracture. In this video, Souza talks about the results of her trial at the CIRM governing board's Spotlight on Disease seminar on March 21, 2012 in Sacramento, California.
