Fig. 6From: Oncolytic therapy with vaccinia virus carrying IL-24 for hepatocellular carcinomaCell-cycle analysis by flow cytometry. SMMC-7721 cells treated with PBS, VG9-IL-24 or VG9-EGFP were harvested after 48 h and stained with PI. Cell cycle distribution was analyzed by flow cytometry and the percentage of cell-cycle phases was analyzed by Flow Jo Software. Each bar represents the mean ± SD of three independent experiments. *P < 0.05; **P < 0.01Back to article page
