New method shows it is possible to grow bone for grafts within a patient's body

...h a layer of special pluripotent cells which, like marrow cells, are capable of transforming into the different types of skeletal tissue. So Shastri and his collaborators decided to create the bioreactor space just under this outer layer. They created the space by making a tiny hole in the periosteum and i...
