Figure 2: Effects of aspirin on cell cycle kinetics of MG-63 cell line determined by flow cytometry. Cultured cells were treated for 24 h with 1, 10, 20, 100, or 1000 μM aspirin. Control group was not treated. G0/G1, S, and G2/M represent the percentage of cells distributed among these phases after treatment, as determined by flow cytometry. We repeated experiments at least three times.
