"Olfactory ensheathing cells (OEC) have been transplanted with success in to the spinal cord of Polish man Darek Fidyka, who was the victim of a knife attack that left him paraplegic in 2010.[4] In 2014, Fidyka underwent pioneering spinal surgery that used OEC grafts to 'bridge the gap' in his severed spinal cord. The surgery was performed in Poland in collaboration with Prof Geoff Raisman, chair of neural regeneration at University College London's Institute of Neurology, and his research team. The olfactory cells were taken from the patients olfactory bulbs in his brain and then grown in the lab, these cells were then injected above and below the impaired spinal tissue.[5] Fidyla regained sensory and motor function in his lower limbs, notably on the side of the transplanted OEC's. He is believed to be the first person in the world to recover sensory function from a complete severing of the spinal nerves." - Wikipedia
