College of Medicine has research stake in final space shuttle mission

When NASA’s final space shuttle mission begins, so will an experiment on bone density by researchers at Penn State College of Medicine. They hope to learn more about the effects of microgravity on the conversion of stem cells to bone forming cells that create bone mass. Dr. Henry Donahue, professor of orthopaedics and rehabilitation, and M.D./Ph.D. student Shane A.J. Lloyd discuss the experiment and its significance.
