Methods:The cells from human fetal cerebellum (8-10 weeks of gestation) were grown and expanded in vitro. The cultured neurospheres were then implanted into the dentate nuclei of patients by stereo tactic operation. Totally,12 patients (7 males and 5 females with age ranging 22-62 years,mean 43 years) were treated by this operation from August 2006 to August 2008. Results:The cells of fetal cerebellum were expanded by 107 folds in undifferentiated state in the culture. After the operation,no rejection was detected. Follow up,the effective rates were 58.3% after 3 months,75.0% after 6 months,and 66.7% for 12-24 months (mean 18 months). Conclusion:the transplantation of in vitro cultured neural stem cell is a feasible and effective treatment for inherited CA,but the long term effectiveness need to be taken in consideration.展开更多

The clinical symptoms are caused by the loss of dopamine and the consequent dysfunction of the nigrostriatal pathway. Neurotrophic factors that may prevent nigrostriatal degeneration by improving the function of remaining dopaminergic neurons has the potential to be a useful therapy for Parkinson’s disease. Neurotrophic factors and their specific receptors could play an important role in the progress of Parkinson’s disease. The neuroprotective effects of neurotrophic factors GDNF, BDNF, IL-6 on dopaminergic neurons in vivo and in vitro , and the potential therapeutic use in treating Parkinson’s disease were discussed in this paper.展开更多
