title: Intracerebral transplantation of bone marrow stromal cells in a 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine mouse model of Parkinson's disease.
abstract: Adult C57BL/6 mice were injected with 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP). Intrastriatal transplantation of bone marrow stromal cells (MSCs) was performed 1 week after MPTP administration. MSCs were harvested from donor adult mice, and then cultured and prelabeled with bromodeoxyuridine (BrdU). MPTP-Parkinson's disease (PD) mice treated with intrastriatal injection of phosphate-buffered saline (PBS), and normal non-MPTP mice were used as controls. MPTP-PD mice with MSC intrastriatal transplantation exhibit significant improvement on the rotarod test (P<0.05) at day 35 compared with PBS controls. Immunohistochemistry shows that BrdU reactive cells survive in the transplanted areas in the MPTP-PD striatum at least 4 weeks after administration. Scattered BrdU reactive cells express tyrosine hydroxylase (TH) immunoreactivity. Our findings suggest that MSCs injected intrastriatally survive, express dopaminergic protein TH immunoreactivity, and promote functional recovery.
