Gene therapy converts dead bone graft to new, living tissue

...d to eventually aid people with various cancers or injuries whose treatment involves the replacement of large sections of bone. Cancers such as osteosarcoma, one of the most common types of bone cancers, or tumors that occur adjacent to bones, often must be treated by removing the diseased section of bone and...
