Figure 4From: Antitumor activity of the selective cyclooxygenase-2 inhibitor, celecoxib, on breast cancer in Vitro and in VivoEffects of celecoxib on the cell cycle of MCF-7 cells by flow cytometry. A: control group; B: 10 μmol/L celecoxib; C: 20 μmol/L celecoxib; D: 40 μmol/L celecoxib. The cell cycle distributions in MCF-7 cells were determined by PI staining and flow cytometric analysis after treated with 0-40 μmol/L celecoxib for 48 h. Results presented were representative of three independent experiments.Back to article page
