摘要
背景:神经干细胞的迁移在神经系统的发育和损伤修复中起着至关重要的作用,近来研究表明趋化因子参与神经干细胞的迁移,但关于其迁移机制目前尚不清楚。目的:观察体外条件下基质细胞衍生因子1对胎鼠海马神经干细胞的趋化迁移作用。方法:通过无血清法体外分离、培养及鉴定胎鼠海马神经干细胞;细胞免疫荧光及RT-PCR检测其CXCR4是否表达;观察不同浓度基质细胞衍生因子1对神经干细胞的趋化迁移作用,中和CXCR4受体以验证基质细胞衍生因子1趋化迁移作用的特异性。结果与结论:胎鼠海马来源神经干细胞表达趋化因子受体CXCR4,呈阳性。RT-PCR琼脂糖凝胶电泳后出现643bp特异性扩增条带。体外条件下基质细胞衍生因子1趋化迁移随浓度而增强,500μg/L为最佳趋化浓度。加入抗CXCR4多克隆抗体中和后,神经干细胞迁移较基质细胞衍生因子1组明显减少,与对照组比较,差异无显著性意义(P>0.05),提示抗CXCR4多克隆抗体可阻断趋化迁移作用。
