The isolation of neural stem cells from the olfactory bulb of Parkinson's disease model
چکیده انگلیسی

Hyposmia is one of the characteristic symptoms of PD. We isolated the neurosphere forming cells (NSFCs) from the olfactory bulb (OB) after dopaminergic neuronal loss induced by 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP), which is a model of Parkinson's disease. We used BrdU to label dividing cells and isolated NSFCs from the OB of adult mice with or without MPTP to confirm the function of OB in PD models. Seven days after MPTP treatment, BrdU-positive cells were significantly increased in the OB, especially in the glomerular layer (GL) and the subependymal zone (SEZ). The number of neurospheres derived from the adult OB was not decreased in groups receiving MPTP, instead, it was significantly increased at 21 days post-injection and only returned to control levels 40 days after MPTP administration. We also evaluated the differentiation of NSFCs into neural subtypes and found that these NSFCs could be well infected with retrovirus. Adult neurogenesis may be enhanced as a repair system in the tyrosine hydroxylase (TH) positive cells of the OB after MPTP administration. The isolation of neural stem cells from the OB after MPTP administration has helped to establish the cellular basis of neurogenesis and supports a role for the transplant-mediated treatment of PD.
