Effects of 13 CpG ODNs on cell proliferation of MCT3T cells. a MTT assay detected MC3T3 cell viability co-cultured with 12 ODNs, ODN 2006 and PBS for 24, 48 and 72 h. 1, FC003; 2, SAT05f; 3, SAT05d; 4, MS19; 5, BW001; 6, FC001; 7, FC002; 8, BW006; 9, YW002; 10, YW001; 11, FC004; 12, MT01. n = 6. *P < 0.05, **P < 0.01 and ***P < 0.001 compared with the control group and ^#P < 0.05, ^##P < 0.01 and ^###P < 0.001 compared with the ODN 2006 group by paired t test. b Cell cycle examination by flow cytometry after co-culture for 72 h. The abscissa indicates FL2-A channels, and the ordinate indicates cell number. c Quantative analysis of cell population in flow cytometry. n = 3. Data represent the mean ± SD of three independent experiments
