Scientists at Cambridge University have reversed the process of development in dogs after administration of paralysis in their body cells that have been grown from the mucous membranes of their own noses, reports "Bi-bi-si."
The research team, however, has already expressed his cautious optimism about what this technology can play a key role in the treatment of people with similar injuries.
We all took part in the experiment, animals were spinal injury, do not let them use his hind legs. This study was the first to provide for transplanting cells to animals with injuries sustained in "real life" instead of laboratory animals.
The dogs in the study were taking olfactory cells present in the mucosa of the nose, which were grown and expanded for several weeks in the laboratory.
Thus, 23 of 34 legged participating in the experiment, these cells were transplanted directly into spinal injury site, while the rest was introduced neutral liquid. Many dogs who underwent transplantation of cells from the lining of the nose, there was a significant improvement, and they could go with the treadmill belt.
"The results of our study are striking, as the first to show that the transplantation of cells of this type in the injured spinal cord may contribute to a significant improvement," - said Professor Robin Franklin, a biologist at the Institute for Stem Cell Wellcome Trust-MRC.
"With this technology we will be able to recover at least part of movement for people with injuries of varying degrees of spinal cord, but to the point where we can achieve the restoration of lost functions, we still have a very long way to go," - he added.
Specialists of the Institute MRC claims that the technology they have developed will be for people with back injuries and disorders of the bowel, bladder and sexual function of vital importance.
