Combination of GF and vinblastine exerted synergistic effects in inhibiting MCF-7 cell proliferation. The median effect plots for the inhibition of cell proliferation in the presence of GF (A) and vinblastine (B) are shown. (C) The effects of the combination of GF and vinblastine (Vinb) on MCF-7 cell proliferation after 48 h treatment are shown as combination index. Data are average of four experiments and error bars represent SD.
