The effect of PS VII treatment on the growth of Hela and End1/E6E7 cell lines. (a) The effect of PS VII at the concentrations of 1, 3, 10, 30, and 100 μM on Hela cells. Common logarithm values of the concentrations were used as the X-axis. Lg1 = 0.0, Lg3 = 0.5, Lg10 = 1.0, Lg30 = 1.5, and Lg100 = 2.0. (b) The effect of PS VII at the concentrations of 1, 3, 10, 30, and 100 μM on the normal cervical epithelial cell line End1/E6E7. (c) The effect of PS VII at the concentrations of 0.8, 1.6, and 2.4 μM on Hela cells. Cell proliferation of Hela cells was evaluated by EdU assays. Red staining showed proliferative cells. Sections were counterstained with Hoechst (blue) to identify the orientation of nuclei (original magnification, ×200).
