Doctors in Sheffield say patients with multiple sclerosis (MS) are showing "remarkable" improvements after receiving a treatment usually associated with cancer.
Steven Storey was diagnosed with MS in 2013 and within a year went from being an able-bodied athlete to needing a wheelchair and losing sensation in much of his body.
He said: "I went from running marathons to needing 24-hour acute care. At one point I couldn't even hold a spoon and feed myself.
Within a few days of the transplant he was able to move his toes, and after four months could stand unaided.
He still needs to use a wheelchair but can manage short distances without any support.
Steven, who is continuing to undergo physiotherapy said: I can swim and cycle and hopefully walking is the next big step.
