Australian doctors are reporting early results of using adult stem cells to mend non-healing bone injuries. Eight of the ten patients treated so far have seen remarkable regrowth and repair of bones, with a ninth patient showing some regrowth. One man's broken bones had failed to heal for 14 months. He told how within weeks after being treated with his own adult stem cells, he threw away his crutches. The Australian company running the clinical trial, Mesoblast, says they will also be initiating trials using donor adult stem cells for bone healing.
