The nerve is expected to repair after human brain injury

The nerve is expected to repair after human brain injury
It is reported ' Reporter Sun GuoGen) Fudan University the intersection of brain and research institute, the intersection of Fudan University and medical the intersection of nerve and the intersection of biology and national key the intersection of laboratory and Yang shake the intersection of key link and Professor, study group, make progress in neural stem-cell research recently. They find that there are neural stem cell and new born neuron in the adult macaque and human brain, and newly neuronal characteristic and migration route produced by the neural stem cell in detailed description for the first time. This achievement brings the new hope for the neural regeneration after human brain injury. Relevant serial theses have already been issued in international mainstream academic periodical " scientific magazine of nerve ", " cell research " and " scientific magazine of European nerve " successively, arouse the attention from people of the same trade at home and abroad. By the neural stem cell " Make " Nerve cell last neuron too,for a long time,think medical circle stem cells neural in the brain, and the lost nerve cell because of disease or traumatism of brain is non-renewable. In recent years, the scientist finds that still there are neural stem cells in the adult mammalian brain, and these stem cells can produce the new nerve cell constantly, but the relevant research before this mainly goes on on little white mouse, distribution state, function to the neural stem cell in primate's brain,etc. are known little about. Been made great efforts for many years, the ones that have comparatively confirmed in the adult macaque's brain in detail finally in Professor Yang ZhenGang and his group have been " made " by the neural stem cell New born for neuron,and track, not explore at characterized " the long distance " in brain in these neurons new borns Move the law. Subsequently, they have found the neural stem cell in the research that the adult human brain that is provided for think tank of Chinese in Wuhan organized, and find this kind of neural stem cell is very active in the brain, can produce the new neuron constantly. They utilize terms strike still method of gene, in normal damaging into adjustment mechanisming in the brain, making and further investigating to neural stem cell, find finally a gene which is named Sp8 plays an important role while the nerve cell is produced and moved at a long distance. Without Sp8 gene, it would not happen in the neural stem cell there should be the function, that is to say, Sp8 gene far exceeds scientist's knowledge of it before to the important function of the neural stem cell.
