London, November 16 (Xinhua) ' The reporter is yellow) It is a kind of cell that can be used for repairing the nervous system to take a sniff at sheath cells, but natural this kind of cell that exists is limited in quantity in the human body, have limited the practical application of the relevant treatment. British scientist delivered a report saying a few days ago, they had found the stem cell origin of taking a sniff at sheath cell, foster and take a sniff at sheath cells in a large amount all right, disease of damaging etc. that help to treat the spinal. It is introduced, take a sniff at sheath cell to exist, protect the intersection of sense of smell and neural cell in the membrane in nasal cavity, the past finding injected it into the nerve fiber of spinal,etc. damaged, contribute to the repair of the nervous system. If adopt taking a sniff at sheath cells of patient, will not lead to the fact the immune system arranges the different response. But taking a sniff at the intersection of sheath and cell to be quantity little natural to exist under membrane under nasal cavity, think it only come from the nasal cavity membrane was organized too in the past, have not " produced in batches " The method to take a sniff at sheath cell, has limited the practical application of this kind of cell. Organization's researchers such as British Cambridge University,etc. say on a new American " journal of national academy of sciences ", take a sniff at sheath cells and still come from a kind of neural ridge stem cell that can be found in skin. Researchers have carried on the experiment with the embryo of chicken and mouse, adding one kind into its neural ridge stem cell can give out protein of the green fluoro, found such green fluorogenic protein in taking a sniff at sheath cells of them too later, prove these take a sniff at sheath cells and come from the neural ridge stem cell. Clare Dr. Bake who carries on research says, the next thing should be done is to find out and foster the method to take a sniff at sheath cell in the laboratory with the neural ridge stem cell.
