Progress in neural stem cells WANG Xuan WANG Kun WANG Xiao2min (Neuroscience Research Institute Peking University Beijing 100083 China) Abstract : Recently the research methods for stem cells from central nervous system and the clinical application have at2 tracted attention of CNS study. In this review the finding of neural stem cells new research techniques and therapeutic effects on the CNS disorders such as neurodegeneration diseases ischema injury and tumors by applying neural stem cells are introduced.

By injection of viral vectors or transplantation of genetically engineered cells into specific sites of the brain the development of technologies for delivery of foreign genes into brain opened the field to promising treatments for CNS disorders. But the development of gene therapy for neurological diseases represents a more complex problem than that for other systemic disorders. Incomplete characterization of target organs ( brain and spinal cord) and additional challenges such as post2mitotic cells heterogeneity of cell types and circuits and limited access all contribute to the difficulties. For this reason this report provides an update outline of gene therapy in CNS and re2 views current researches in this filed.
