Abstract:

BACKGROUND: The use of neural stem cells provides a new approach for nervous system functional reconstruction and nerve regeneration. How to solve the induced differentiation of neural stem cells is still a research hotspot.
OBJECTIVE: To investigate the differentiation of rat neural stem cells into neurons and dopaminergic neurons under induction of glial cell-line derived neurotrophic factor gene.
METHODS: PcDNA3-GDNF-GFP plasmids were constructed and transferred via lipidosome into rat embryonic neural stem cells. Differentiation of neural stem cells after transfection was identified under a fluorescence microscope. Immunofluorescent staining was used to detect expression of β-tubulin III and tyrosine hydroxylase.
RESULTS AND CONCLUSION: At 3 days after transfection, green fluorescence was observed in the transfected cells that were globular. At 7 days after transfection, the proportion of neural stem cells differentiating into neurons and dopaminergic neurons were significantly increased. These results indicate that the glial cell-line derived neurotrophic factor gene can induce the differentiation of neural stem cells into neurons and dopaminergic neurons.
