SGC-7901 cell proliferation increased by hCG. Cells at a density of 2×10³ cells per well in 96-well plates were cultured for 5 days with hCG at concentration of 0, 0.09 and 0.89 IU/ml. Cell proliferation was measured at 450 nm using a plate reader using following treatment with cell counting kit-8 dye. Data represent the mean ± SD of 3 experiments at each concentration. *P<0.01 and **P<0.001 with comparisons shown by lines. hCG, human chorionic gonadotropin; DMSO, dimethylsulfoxide.
