摘要：OBJECTIVE: The motor symptoms of Parkinson's disease (PD) can be improved by cell transplantation,which has caught general attention from the field of the therapy for PD recently. In this paper, we summarize the cell-based therapy for PD.DATA SOURCES: A search for English literature related to the cellular transplantation of PD from January 1979to July 2006 was conducted in Medline with the key words of "Parkinson's disease, cell transplantation,embryonic stem cells, neural stem cells".STUDY SELECTTON: Data were checked in the first trial, and literatures about PD and cell transplantation were selected. Inclusive criteria: ① PD; ② Cell transplantation. Exclusive criteria: repetitive researches.DATA EXTRACTTON: A total of 100 papers related to cellular transplant and PD were collected and 41literatures were in accordance with the inclusive criteria.DATA SYNTHESIS: PD is a neural degeneration disease that threatens the health of the aged people, and most traditional therapeusis cannot delay its pathological proceeding. Cell transplantation is becoming popular as a new therapeutic tool, and the cells used to transplant mainly included dopamine-secreting cells, fetal ventral mesencephalic cells, embryonic stem cells and neural stem cells up to now. Animal experiment and clinical test demonstrate that cell transplantation can relieve the motor symptoms of Parkinson's disease obviously, but there are some problems need to be solved.CONCLUSTON: Cell transplantation has visible therapeutic efficacy on PD. Following the improvement of technique, and we have enough cause to credit that cell therapy may cure PD in the future.
