The nose can be related to the spine

In 2010 Darek Fidyka was paralyzed from the chest down in a knife attack. He now can walk after scientists transplanted cells from his nasal cavity into his spinal cord. The secret is that some cells in the nose regenerate throughout our adult life. The scientists moved some of these cells from his nose to his spine.

It's true that he cannot walk without aid; he uses something called a frame in England. It took about three months before Fidyka began to notice changes in his body as his left thigh began putting on muscle. Three months later he took his first steps along parallel bars, using leg braces and the support of a physiotherapist. Two years after the treatment, he can now walk outside the rehabilitation center using a frame. He has also recovered some bladder and bowel sensation and sexual function. He works hard: he exercises five hours per day, five days a week.
