A man who was paralyzed from the chest down after a knife attack in 2010 can now ride an adapted tricycle. In 2014, surgeons in Poland announced they had reversed Darek Fidyka's paralysis by using cells taken from his nose to repair his spinal cord.

The head of the project, surgeon Dr. Pawel Tabakow said: "If we can bridge the gap between the two spinal cord stumps then there will be no doubt that our technique works and this will be historic - if we succeed - we will have found a cure for paralysis."
