Proliferation of primary HUVECs (A) and HUV-ST (B) cells. Cells were stimulated without or with 0.733, 7.33, 73.3 and 600 ng/ml of rhFSH or 50 ng/ml of rhVEGF used as a positive control. Each bar represents the mean ± SEM of three independent experiments with n = 8 per treatment. Asterisks indicate differences between control and stimulated cells (***P < 0.001).
