摘要: 目 的 筛选出适宜的血清及秋水仙碱的作用浓度及时间,使乳腺癌MCF-7 细胞分别达到G0/G1 和G2/M 期同步化。方 法 采用血清饥饿法诱导MCF-7 细胞G0/G1 同步化,秋水仙碱诱导细胞G2/M 期同步化,流式细胞仪检测细胞各期分布情况。结 果 处理24 h 后,1%血清浓度组G0/G1 期细胞分别达到(72. 96 ± 0. 84)%,1. 0 μg/mL 秋水仙碱处理组G2/M 期细胞分别占总细胞数(73. 67 ± 1. 77)%。处理36 h 后,1%血清浓度及秋水仙碱实验组细胞发生凋亡。结 论 MCF-7在血清浓度为1%处理24 h后完成G0/G1同步化,在1. 0 μg/mL 的秋水仙碱处理24 h后完成G2/M期同步化。

Abstract: Objective This experiment is conducted to select the appropriate concentration and time of serum and colchicine to synchronize breast cancer MCF- 7 cells at G0/G1 and G2/M phases, respectively. Methods MCF-7 was treated with different serum concentration to induce cell at G0/G1 stage synchronization,and treated with colchicine reagents to induce cell at G2/M synchronization. Cell cycle distribution was analyzed by flow cytometry for 12,24,36 h. Results After 24 hours treated,in 1% serum concentration group,the percentage of MCF-7 at G0/G1 accounted for(72. 96 ± 0. 84)%;in 1. 0 μg /mL colchicine reagent group,the percentage of MCF-7 at G2/M stage was(73. 67 ± 1. 77)%. 36 hours after treatment,in experiment groups of 1% serum and the group of colchicine, cell apoptosis was induced. Conclusion In experimental groups,1% serum treating and 1. 0 μg/mL colchicine regents treating for 24 h can basically completed cell cycle synchronization at G0/G1 and G2/M phases,respectively.

Key words: serum starvation, cell cycle synchronization, colchicine regents, apoptosis, G0/G1, G2/M
