Ndrg2对培养大鼠神经干细胞增殖和分化的影响
[Abstract]:Aim: to detect the expression of Ndrg2 in cultured rat neural stem cells (NSCs) (NSCs) and to explore the effect of Ndrg2 expression on the proliferation and differentiation of NSCs. Methods: the expression of Ndrg2 in cultured NSCs was detected by immunocytochemical staining and Western Blot assay. After NSCs was infected with AAV-Ndrg2 overexpression virus and LV-Ndrg2-RNAi interference virus, the proliferation of NSCs was observed by BrdU incorporation assay after Ndrg2 expression was interfered with. The differentiation of NSCs was analyzed by immunocytochemical staining of neuronal marker Tuj1 and star glial cell marker GFAP. Results: Ndrg2 was highly expressed in rat NSCs. Compared with the control group (infected with empty vector of virus), the up-regulation of Ndrg2 expression could significantly increase the number of BrdU~ and Tuj1~ cells (P 0.05), but the number of GFAP~ cells did not change significantly (P 0.05). On the contrary, down-regulating the expression of Ndrg2 decreased the number of BrdU~ cells (P 0.05), but did not affect the number of Tuj1~ and GFAP~ cells (P 0.05). Conclusion: the expression of Ndrg2 in rat NSCs, can positively regulate the proliferation of NSCs and promote the differentiation of NSCs into neurons.
