[Intraparenchymal and intraventricular transplantation of fetal substantia nigra cell suspension in rat model of Parkinson's disease].

The grafts of fetal substantia cell suspension grafts could bring into a behavioral effect and characteristics of histology and immunocytochemistry in rat models of PD after the grafts were transplanted either into the lateral ventricles or directly into the striatum. It was found that the intraparenchymal tromsplantation of fetal nigral cell suspensions not only was beneficial to reinnervation between host and grafts, but also produced more complete and steady effects than the intraventricular transplantation. We concluded that the restoration of nervous functional deficits of PD rats is likely to depend on both extensive dopaminergic reinnervation throughout the grafted sites and on closer integration of the grafts with the host striatal circuitry.
