CAMBRIDGE, England (UPI) -- A revolutionary transplant operation has allowed paralyzed dogs to walk again and may also benefit paralyzed human patients, British scientists said.
Researchers at the University of Cambridge said the pet dogs had all suffered serious damage to their spinal cords that left them unable to walk normally with their hind legs.
After specialized cells from the dogs’ noses were transplanted to the damaged nerves, most of the pets recovered their lost mobility and some were able to walk and even run on all four legs, The Independent reported Monday.
The technique, in which olfactory ensheathing cells from the nasal cavity are transplanted to the spinal cord, could have human applications, the researchers said.
“Our findings are extremely exciting because they show for the first time that transplanting these types of cell into a severely damaged spinal cord can bring about significant improvement,” Cambridge researcher Robin Franklin said.
Olfactory ensheathing cells protect the regrowth of nerve cells in the olfactory center just below the brain, cells that must be able to regenerate because they are susceptible to damage from the outside environment, Franklin said.
“We’re confident that the technique might be able to restore at least a small amount of movement in human patients with spinal cord injuries, but that’s a long way from saying that they might be able to regain all lost functions,” he said.

'뒷다리 마비된’ 개, 다시 걸은 사연!
영국의 과학자들의 노력으로 하반신이 마비되어 걸을 수 없었던 개가 코에서 떼어낸 세포를 척수에 이식하는 치료를 통해 기적적으로 다시 걷게 되어 화제가 되고있다.
캠브리지 대학교 연구팀은 척수에 심각한 손상을 입어서 뒷다리를 사용하여 정상적으로 걷는 것이 불가능했었던 애완견들에게 치료를 시행했다.
애완견들의 코에서 떼어낸 특수 세포들을 손상된 신경에 이식한 후, 대부분의 애완견들은 운동신경을 되찾았고 일부 애완견들은 걷거나, 심지어 네 발로 뛰기까지 했다고 영국 현지 언론은 전했다.
이 수술 방법은 인간에게도 적용될 수도 있다고 과학자들은 밝혔다.
코에 있는 이 후각의 세포들은 뇌 바로 밑에 후각 센터에 있는 신경세포들의 재성장을 돕는다.
캠프리지 연구원 로빈 프랭클린은 "척추에 손상을 입은 사람들도 이 수술을 적용시키면 적은 양의 운동이라도 회복될 지도 모른다"라고 말했다.
