It is reported ' Intern reporter Gu WeiJia and Xu RuiZhe) The scientist of our country has found the neural stem cell's unique manner in the damaged brain, have offered the new thinking for the neural stem cell moved and transplanting, many kinds of brain injury of treatment. The internationally recognized academy periodical " scientific magazine of nerve " published yesterday has issued the originality scientific findings of the research institute of brain of Fudan University, and as the intersection of light spot and the intersection of article and key introduction, with a million readers the intersection of U.S.A. and " the scientific news " magazine go on the report to these research too. It mentions to be can changeable regenerated stem cell, people mostly can think of hematopoietic transplantation of stem cell, it is widely used in clinical treatments such as leukemia,etc.. But the intersection of Fudan University and the intersection of brain and the intersection of academy of sciences and Yang shake the intersection of key link and seminar, verify neural stem cell it possesses hematopoietic stem cells to be so getting all-round, can't mend brain injury, but necessary manual intervention automatically. President Professor Ma Lan thinks, the researcher has not stuck to the established practice, has confined in the major view in the west, one may well say that takes the course of its own. For a long time, there is a view in the western neural stem cell's research field: The reason why the brain can't repair oneself, because there is too less neural stem cell's quantity in the brain, so long as try every means to amplify the cell quantity, can solve the problem. And the scientific research personnel of Fudan University find, the neural stem cell even the quantity is enough, can't develop and " rebuild " either The particular neuron that the nervous system needs, seminar members say: "This just as after the house collapses, need more fragments of brick to rebuild it, but the building materials shipped are only stones. " The neural stem cell exists in the brain all one's life, it is a potential nervous system " repairman " . As genetic technology develops, the mankind can already utilize a skin cell safely, change it and get back to embryo -like cells, then succeed in cloning out the animal. In view of the new achievement of Fudan University, the scientists may induce the neural stem cell, make it develop, split up and become the new born neuron that patients such as senile dementia, Parkinson disease,etc. need, in order to repair the nervous system that is damaged. But Yang ZhenGang points out, before this technology has not made the break-through, any clinical treatments utilizing the neural stem cell to transplant briefly should be very prudent. [The expert comments on ] " scientific magazine of nerve " goes over a manuscript or draft to think: This important discovery will change the understanding of neural stem cell of biological educational circles of regenerated nerve.
