The trial is being conducted by the Royan Institute in Tehran and expects to enrol 24 subjects by April 2014. Participants will receive cell from their own bone marrow (CD133+ cells) in multiple injections directly into the fluid around spinal cord (intrathecal injection). Participants will be monitored for complications, as well as changes in their clinical condition.
