Scientists discover a new hope for humans with spinal injuries by reversing paralysis in dogs after injecting cells grown from their nasal lining. Scientists have suggested that this accomplishment would be important for patients of spinal problems who have had lost sexual prowess and control on their bowel and bladder movements.
The 34 treated pets had suffered major spinal injuries due to which their back legs couldn’t function. The olfactory ensheathing cells from the lining of the nose of the injured dogs were removed to grow and expand extensively in the lab. Out of the total number of dogs, cells were transplanted in the injured area in 23 dogs and cells were injected with a neutral fluid in the rest of the dogs. Dogs that were treated with transplantation were able to move on a treadmill with aid of a harness.
Researchers at the Cambridge University are optimistic about the use of this technique in the treatment of humans. Professor Robin Franklin, co-author of the study, said that the findings of their experiment are extremely interesting because it is first of its kind to show how transplantation of cells into an injured spinal cord can result in considerable improvements. However, further study is required to know whether all lost functions of the spinal cord can be regained or a few.
