Gene therapy converts dead bone graft to new, living tissue

... If calcium, which is necessary for such important functions as maintaining the brain and heart, runs low, cells called osteoclasts dig out the calcium from our bones. This is why doctors encourage post-menopausal women to take calcium supplements, so that the body doesn't raid their bones for the calcium it n...
