  • Effects of Bone Morphogenetic Protein-2 on Expression of DLX5 of the Neural Stem Cells of Anterior Subventricular Zone

    【摘要】 目的 探讨骨形成蛋白-2(bone morphogenetic protein-2,BMP-2)对室管膜前下区(anterior subventricular zone,SVZa)神经干细胞DLX5表达的影响。 方法 体外培养SVZa神经干细胞,用BMP-2及其拮抗剂Noggin诱导SVZa神经干细胞,分别用免疫荧光染色和逆转录-聚合酶链反应(RT-PCR)检测DLX5表达变化。 结果 BMP-2组SVZa神经干细胞DLX5蛋白表达和DLX5mRNA表达水平明显高于对照组(Plt;0.05),且该效应能被其拮抗剂Noggin特异性地抑制。 结论 BMP-2是DLX5上游调节基因,可促进SVZa神经干细胞DLX5的表达。【Abstract】 Objective To investigate the effect of bone morphogenetic protein-2 (BMP-2)on expression of DLX5 of neural stem cells in anterior subventricular zone (SVZa). Methods The neural stem cells of SVZa were separated and cultured in vitro, which were induced by BMP-2 and Noggin.Immunofluorescence staining and RT-PCR were employed to assay the expression of DLX5. Results The percentages of expression of DLX5 protein and DLX5 mRNA in BMP-2 group were much higher than those in the control group (Plt;0.05). And this induction could be specifically blocked by Noggin. Conclusion BMP-2 is an upstream gene of DLX5; BMP-2 can promote the expression of DLX5 of the neural stem cells of SVZa.
