Stem cell jab restores feeling in paralysed

London (tip): Scientists have developed a new stem cell therapy which can help people with broken spines to recover feelings in previously paralysed body areas.

Two of the three patients have reported a positive outcome after receiving injections of neural stem cells, doctors at the Zurich University said. Doctors say the ultimate aim is to help those paralysed by injury to walk again, The Telgraph reported.

The trial worked on the theory that injected adult stem cells would transform themselves into spinal cord nerves, reconnecting brain and lower body.

Professor Armin Curt, who lead the study, described the result as “fundamental” .

“To find something that can repair the spinal cord is a huge breakthrough. If we can show that something has changed for the better (as a result of stem cell therapy) that’s fundamental,” he said.

He presented the findings at the annual conference of the International Spinal Cord Society in London on Monday.
“We think these stem cells are one of the first tools we have for actually repairing the central nervous system. To see this kind of change in patients who truly have the worst-of-the-worst type of injury to the spinal cord is very exciting,” Dr Stephen Huhn, from the firm, said.

The three patients, who all had complete spinal injury and could feel nothing below their nipples, were each given a dose of 20 million ‘adult’ neural stem cells about six months ago. This was primarily a safety trial, and Curt said monitoring had shown “a very good safety profile”.

Detailed questioning and objective tests also showed signals were passing up the injured spine to the brain, when they had not before.

One of the patients, a 46-year-old Norwegian financial consultant, said, “I’ve noticed changes. When somebody touches my stomach, I can feel something. I can’t be specific, but I can sense it.”
Stem cell research for spinal injury “requires an incremental approach where we build the therapy one brick at a time” , Huhn said. Walking was not the only aim: people paralysed also wanted to regain sensation, bowel and sexual function, he said.
