摘要 目的建立更加科学且简易的新生SD大鼠皮质神经元缺氧模型的方法.方法取24h内的新生SD大鼠皮质,用木瓜酶和DNaseⅠ共同消化,10%FBS的DMEM/F12培养液终止消化,用10%FBS的DMEM/F12种植培养,4h后换成无血清neurobasal配制的维持培养液,未加入阿糖胞苷培养,允许部分胶质细胞生长,第9天用免疫荧光法鉴定神经元的纯度,7~10d用于缺氧模型,在37℃、无糖DMEM、高纯N2环境中缺氧1~6h,观察皮质神经元缺氧后形态学的变化,根据实验目的选择最适合的缺氧时间,建立缺氧模型.结果培养第10天,神经元胞体饱满,结构清晰完整,神经元纯度荧光鉴定结果为82.04%.随着缺氧时间的增加,皮质神经元胞体和突起逐渐经历水肿到裂解的过程.结论有部分胶质细胞的生长,建立了更加科学且简易的新生SD大鼠皮质神经元缺氧模型.
