AFP: Paralyzed woman walks again after stem cell therapy

This still has to be confirmed, but if true it would be outright amazing:

A South Korean woman paralyzed for 20 years is walking again after scientists say they repaired her damaged spine using stem cells derived from umbilical cord blood.

Hwang Mi-Soon, 37, had been bedridden since damaging her back in an accident two decades ago.

They said it was the world’s first published case in which a patient with spinal cord injuries had been successfully treated with stem cells from umbilical cord blood.

Though they cautioned that more research was needed and verification from international experts was required, the South Korean researchers said Hwang’s case could signal a leap forward in the treatment of spinal cord injuries.

The use of stem cells from cord blood could also point to a way to side-step the ethical dispute over the controversial use of embryos in embryonic stem-cell research. AFP

No embryos died to make this happen. How could you possibly bring up any ethical counter-arguments to argue against such uses of stem cells?
