Survival and migration of neural stem cells in the brain of mice after ventricle transplantation / 中国康复理论与实践

ABSTRACT

@#ObjectiveTo investigate the survival and migration of the neural stem cells(NSC) in the cerebrospinal fluid (CSF) circle of mice after ventricle transplantation. MethodsNSC labeled with green fluorescence protein (GFP) were implanted into the lateral cerebral ventricle of the mice. The mice were killed at time point of 24 h, 48 h, 2 weeks and 10 weeks after transplantation. The brain sections were observed and the behaviors of the mice were evaluated. ResultsGFP-positive cells were found in the lateral cerebral ventricle.Some of them migrated into the parenchyma and located in fibria-fornix, hippocampus,corpus callusum, septum,subventricle zone and beside the blood vessels at the time point of 2 weeks and 10 weeks. There were no obvious complications occured during operations which affected the outcome of growth and development. ConclusionNSC not only can survive, but also can migrate into the local parenchyma of the brain after ventricle transplantation. There were no obvious complications occured after the transplantation of NSC.
