Transplantation of bone marrow stromal cells containing the neurturin gene in rat model of Parkinson's disease.
Brain Res. 2007 Apr 20; 1142:206-16.BR

Abstract

The experiment was to evaluate the therapeutic benefit of transplanted bone marrow stromal cells (BMSCs) transfected with a kind of neurotrophic factor gene, neurturin (NTN) gene, in treating the rat model of Parkinson's disease (PD). The 6-OHDA-lesioned rats were assigned to one of three groups, those receiving BMSCs transfected with NTN gene, those receiving untransfected BMSCs containing a void plasmid and those receiving phosphate buffer solution (PBS). Treatments were injected into the right striatum (6-OHDA-lesioned side). One to six months post-transplantation, apomorphine-induced rotational behavior was observed. One month after transplantation, green fluorescent protein (GFP)/NTN, GFP/glial fibrillary acidic protein (GFAP), GFP/neuron specific enolase (NSE) and GFP/tyrosine hydroxylase (TH) fluorescence determinations of brain sections were carried out. One to six months after transplantation, brain sections containing striatum and substantia nigra were stained for TH. In situ hybridization and Western blots were used to determine NTN mRNA and protein concentration, respectively, in affected brain regions. High performance liquid chromatography (HPLC) was used to measure the dopamine (DA) content in the lesioned striatum 1 and 3 month(s) post-transplantation. The results were shown that: in the first 3 months after transplantation, the number of rotations was lower in NTN-transplant group than the void vector group, and during 1-6 months post-transplantation, the number of rotations was lower in both transplant groups than that in the PBS group (P<0.05). One month after transplantation, we detected GFP/NTN-, GFP/GFAP- and GFP/NSE-labeled cells in the transplantation area of the NTN-transplanted group, but no obvious GFP/TH labeled cells were found. Quantitative analysis of TH-positive cells 1 to 6 months after transplantation indicated that there were no significant differences between groups in survival rates of TH-positive neurons in the lesioned substantia nigra (P>0.05). In situ hybridization and Western blot identified NTN mRNA and protein expression in the transplantation area of the NTN-transplanted group. After transplantation of NTN-expressing cells, DA content in the lesioned striatum was significantly higher in the transgenic group than that in the void vector group or the PBS group (P<0.05). The overall therapeutic effects of the NTN-transplanted group were superior to those of the void plasmid group and the PBS group. The mechanisms by which transgenic therapy treats PD might involve functional enhancement of residual dopaminergic neurons by NTN, which significantly reduces the number of rotations in animals, but not increase the numbers of existing dopaminergic neurons.
