转瓶变速培养对微胶囊肝细胞聚集体形成及活性的影响
目的:观察匀速与变速旋转培养对微胶囊HepLL永生化人肝细胞、HepG2肝细胞聚集体形成和活性的影响。方法:一步法海藻酸钠—壳聚糖( AC)微胶囊包裹HepG2及HepLL细胞,随机分为两大组,每组按转速分3小组。动态观察并测量各组聚集体大小、数目变化,ELISA动态检测各组白蛋白合成量,比色法检测氨的清除量,高效液相色谱法检测安定转化功能。结果:与匀速旋转培养组相比,变速旋转培养组微胶囊细胞第6、8、10、12、14、16天聚集体平均个数、平均最大径、白蛋白合成量、氨清除量以及安定转化量均明显提高(均P<0.01),微胶囊HepLL各组在各个时间点的白蛋白合成量、氨清除量及安定转化功能均优于...

Summary: | 目的:观察匀速与变速旋转培养对微胶囊HepLL永生化人肝细胞、HepG2肝细胞聚集体形成和活性的影响。方法:一步法海藻酸钠—壳聚糖( AC)微胶囊包裹HepG2及HepLL细胞,随机分为两大组,每组按转速分3小组。动态观察并测量各组聚集体大小、数目变化,ELISA动态检测各组白蛋白合成量,比色法检测氨的清除量,高效液相色谱法检测安定转化功能。结果:与匀速旋转培养组相比,变速旋转培养组微胶囊细胞第6、8、10、12、14、16天聚集体平均个数、平均最大径、白蛋白合成量、氨清除量以及安定转化量均明显提高(均P<0.01),微胶囊HepLL各组在各个时间点的白蛋白合成量、氨清除量及安定转化功能均优于HepG2(均P<0.01)。结论:微胶囊转瓶变速培养显著加快微胶囊HepLL、HepG2细胞聚集体形成并提高细胞活性,未来HepLL有可能代替HepG2用于人工肝治疗。 |
