Spinal cord injuries remain one of the most difficult medical problems to treat. But a new groundbreaking surgery has been carried out in China, giving hope that paralysed people may one day walk again.
The regenerative stem cell treatment follows more than 10 years of research by Chinese scientists. The four hour long surgery was conducted in Tianjin.

The doctors treating him have implanted stem cells into his spinal column, using regenerative nerve material developed at the Chinese Academy of Sciences. It's the first time regenerative spinal cord surgery has been attempted, anywhere in the world.
A scar was formed in the first surgery to occupy the entire damaged part of the spine. We then cut it out, about 2.8 centimeters in size, and replaced it with a tube containing stem cells," said Tang Fengwu, China Police Neurological Hospital.
The experiment in animal models was begun in The Institute of Genetics and Development at the Chinese Academy of Sciences ten years ago.
They started with mice, and then progressed to bigger animals, like dogs. The experiments were successful.
Dai Jianwu, research fellow at Inst. of Genetics & Dev't, CAS said that, "Spinal nerves are like a cable. So we've designed collagenous fibers, like a bridge or a rail, that nerves can crawl along as they grow. Stem cells can produce regenerative tissue elements, so they improve the regeneration capacity of the wounded area."
Another six paralyzed patients are now set to take the groundbreaking surgery. New hope for six more families and perhaps a huge breakthrough for spinal cord injuries, across the world.
