摘要
背景:DMEM和RPMI-1640是两种最常用的商品化培养基,二者对肝癌细胞生长的影响尚未见直接的对比研究。目的:比较两种常用培养基对人肝癌BEL-7402与HepG-2细胞系体外生长和增殖效果的影响,从中选择更适合的培养基。方法:分别应用高糖DMEM与RPMI-1640完全培养液培养BEL-7402和HepG-2细胞,于培养的0,24,48,72,96,120h用酸性磷酸酶检测法测定细胞生长和增殖速率,并于倒置显微镜下观察细胞的形态。结果与结论:结果发现BEL-7402和HepG-2细胞在RPMI-1640培养基中的生长增殖速率均明显高于DMEM培养基(P<0.01)。镜下观察证实细胞在RPMI-1640培养基中的黏附和伸展状态更好。因此,建议首选RPMI-1640培养基进行肿瘤细胞体外培养。
BACKGROUND: The most popular commercialized media are DMEM and RPMI-1640. Yet direct comparative study of the two popular media on the influence of liver cancer cell growth has not been reported. OBJECTIVE: Compare the effect of two popular culture media on growth and proliferation of human hepatocarcinoma BEL-7402 and HepG2 cells, in order to find a more suitable medium. METHODS: BEL-7402 and HepG2 cells were cultured in complete growth media prepared with either the high glucose-DMEM or the RPMI-1640 medium. Growth and proliferation rates were detected at timed intervals by the acid phosphatase assay. Cellular morphology was observed under an inverse light microscope. RESULTS AND CONCLUSION: Compared with the DMEM medium, BEL-7402 and HepG2 cells cultured in the RPMI-1640 medium showed a significantly higher growth and proliferation rates (P〈0.01 ). The cells also revealed better adhesive and stretching status in the RPMI-1640 medium, as confirmed under a microscope. The RPMI-1640 medium is the first choice for tumor cell cultures.
