Antitumor Activity of Chinese Propolis in Human Breast Cancer MCF-7 and MDA-MB-231 Cells

Figure 2

EECP decreased MCF-7 and MDA-MB-231 cells proliferation but had little/small effect on normal HUVECs. (a) EECP inhibited MCF-7 proliferation at 24 and 48 h. (b) EECP inhibited MDA-MB-231 cells proliferation at 24 and 48 h. (c) EECP had little effect on normal HUVECs viability under the concentration of 100 μg/mL (^∗𝑃<0.05, ^∗∗𝑃<0.01 versus control, 𝑛=3). Data are means ± S.E.M.
