The patient became unconscious with serious head injuries he suffered in a traffic accident last December.

　　But an operation to transplant 3.2 million purified embryo nerve stem cells into his body revived him.

　　Four days after the operation, the patient came round, and gradually recovered the strength of his limbs. He could also take food by himself, according to doctors in charge of his case.

　　Currently, the movement barriers of the patient have been removed completely. His physical functions have come back to a normal state with the stiff muscles caused by the long-time contracture becoming soft and flexible again.
