The tragedies of Christopher Reeve and others like him who have suffered paralysis from spinal cord trauma may be reversible by using stem cells to replenish damaged and severed nerve cells in the spinal column. The dire shortage of organs for those needing transplants can be reduced by creating an organ designed specifically from the patient’s stem cells in a lab setting to guarantee acceptance by the patient’s body....
