Abstract： 目的系统分析ndrg2在胎前脑组织中表达分布的时空特点,以期明确ndrg2在胎前脑脑功能区的组织分布、细胞定位及表达趋势,为进一步研究其功能提供实验依据.方法收集引产4～7月胎脑组织标本,分别进行组织石蜡切片和总RNA提取,应用免疫组化方法和RT-PCR技术检测ndrg2在蛋白质及mRNA表达水平变化规律.结果免疫组化结果表明,在上述胎前脑脑区神经元细胞胞浆中均有ndrg2蛋白不同程度的表达.RT-PCR结果显示,ndrg2 mRNA在正常胎脑各脑区均有表达;随脑组织发育成熟,ndrg2表达水平增高,4月胎脑中海马ndrg2表达水平较高,而到7月额叶、顶叶则表达增强.以上结果表明,ndrg2基因在不同脑功能区广泛表达,但不同时期、不同胎脑功能区域表达有明显区别.结论在脑发育的过程中,ndrg2表达呈一定时空特点,ndrg2可能对神经细胞发育成熟有一定影响.
