Japan trial to treat spinal cord injuries with stem cells

TOKYO: A team of Japanese researchers will carry out an unprecedented trial using a kind of stem cell to try to treat debilitating spinal cord injuries, the specialists said on Monday. The team at Tokyo’s Keio University has received government approval for a trial using so-called induced Pluripotent Stem (iPS) cells -- which have the potential to develop into any cell in the body -- to treat patients with serious spinal cord injuries.

The trial, expected to begin later this year, will initially focus on four patients who suffered their injuries just 14 to 28 days beforehand, the university said. The team will transplant two million iPS cells into the spines of the patients, who will then go through rehabilitation and be monitored for a year.

The strict limitations on the number of participants is necessary because the process is an "unprecedented, world first clinical trial", the university added. "It’s been 20 years since I started researching cell treatment. Finally we can start a clinical trial," Hideyuki Okano, a professor of physiology, said at a press conference.

The study will be carried out on patients aged 18 or older who have completely lost their motor and sensory functions. There are more than 100,000 patients in Japan who are paralysed due to spinal cord injuries but there is no effective treatment.
