摘要 目的比较50%胎牛血清、油酸分别建立HL-7702细胞脂肪肝的离体细胞模型的优缺点。方法采用50%胎牛血清、油酸分别建立HL-7702细胞脂肪肝的离体细胞模型,并用四甲基偶氮唑盐法检测细胞活性,油红O染色观察细胞内脂滴数量、甘油-3-磷酸氧化酶法检测细胞内甘油三酯含量,比较两种方法的优缺点。两组计量数据比较用t检验,多个样本均数比较采用方差分析。结果0.5mmol/ml油酸组和50%胎牛血清组都能建立较好的肝细胞脂肪变性模型,其中0.5mmol/ml油酸诱导的细胞脂变更为明显,细胞内甘油三酯含量为(893.2±89.1)μg/mg,50%胎牛血清组细胞内甘油三酯含量为(411.6±126.6)μg/mg,两组比较,F=72.288,P〈0.01,差异有统计意义。结论0.5mmol/ml油酸诱导的肝细胞脂肪变性模型具有实用性和可重复性。该模型为非酒精性脂肪性肝病的研究提供了一条有效、简便、可行的新途径。 Objective To compare two models of nonalcoholic hepatocellular steatosis. Methods HL-7702 cells were incubated with a mixture of of unsaturated oleate acid or 50% fetal bovine serum to induce fat-overloading. Significant fat accumulation was documented by Oil Red O staining, and intracellu- lar triglyceride levels was detected by triglyceride enzymatic assay. Results The results showed that both 0.5 mmol/ml oleate acid and 50% FBS were able to induce nonalcoholic hepatocellular steatosis. Conclusion A nonalcoholic hepatocellular steatosis was induced by 0.5 mmol/ml oleate acid.
