Influence of the cell cycle arrest of S phase by 10f in Bel-7402 cells: Bel-7402 cells were incubated with the indicated concentrations of 10f for 24 h and the cells were stained with propidium iodide (PI). Cellular DNA content, for cell cycle distribution analysis, was measured using a flow cytometer. The diagrams show the distribution of the cells according to their DNA content. The inserts give the percentages of cells in different cell cycle phases.
