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

Figure 7

EECP increased ROS level in MCF-7 and MDA-MB-231 cells. (a) Fluorescent micrographs of MCF-7 cells obtained at 48 h (×200). (b) Relative quantity of ROS in MCF-7 cells. (c) Fluorescent micrographs of MDA-MB-231 cells obtained at 48 h (×200). (d) Relative quantity of ROS in MDA-MB-231 cells. Values represent the relative fluorescent intensity determined by laser scanning confocal microscopy (^∗𝑃<0.05, ^∗∗𝑃<0.01 versus control, 𝑛=3).
