目的 探讨与胰腺内皮细胞共培养时C3A细胞功能变化.方法 选择C3A细胞与胰腺内皮细胞的密度比例为10:1分别进行直接和间接共培养7 d,同时设立空白对照组,观察各实验组细胞生长和形态特征,分别用杜邦全自动生化分析仪、放射免疫分析法和ELISA法检测培养液中AST、ALT漏出量,白蛋白含量和安定代谢量.结果 C3A细胞与胰腺内皮细胞直接共培养第5、7天能显著降低ALT、AST的漏出量,第7天提高白蛋白合成量最高达12.977μg/ml和提高安定代谢能力;C3A细胞与胰腺内皮细胞间接共培养在第5、7天也能显著提高白蛋白合成量到7.380μg/ml、10.773μg/ml.结论 与胰腺内皮细胞直接与间接共培养均能明显改善C3A细胞的功能.
