It should be noted that this miracle of science ocurred using umbilical cord stem cells, and not the heavily politicized embryonic variety.

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.

Last week her eyes glistened with tears as she walked again with the help of a walking frame at a press conference where South Korea researchers went public for the first time with the results of their stem-cell therapy.

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.

This is good news for everyone, should it turn out to be true, because we may have a new and ethically unambiguous way of changing peoples’ lives. I’d say it’s about time for a confusing metaphor.

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.

We have glimpsed at a silver lining over the horizon,” said Song Chang-Hoon, a member of the research team and a professor at Chosun University’s medical school in the southwestern city of Kwangju.

Clinical trials with embryonic stem cells are believed to be years away because of the risks and ethical problems involved in the production of embryos — regarded as living humans by some people — for scientific use.

In contrast, there is no ethical dimension when stem cells from umbilical cord blood are obtained, according to researchers.

Additionally, umbilical cord blood stem cells trigger little immune response in the recipient as embryonic stem cells have a tendency to form tumors when injected into animals or human beings.

For the therapy, multipotent stem cells were isolated from umbilical cord blood, which had been frozen immediately after the birth of a baby and cultured for a period of time.

Then these cells were directly injected to the damaged part of the spinal cord.

“Technical difficulties exist in isolating stem cells from frozen umbilical cord blood, finding cells with genes matching those of the recipient and selecting the right place of the body to deliver the cells,” said Han Hoon, president of Histostem, a government-backed umbilical cord blood bank in Seoul.

Han teamed up with Song and other experts for the experiment.

They say that more experiments are required to verify the outcome of the landmark therapy.

“It is just one case and we need more experiments, more data,” said Oh Il-Hoon, another researcher.

“I believe experts in other countries have been conducting similar experiments and accumulating data before making the results public.”
