Role of cell adhesion signal molecules in hepatocellular carcinoma cell apoptosis

Figure 2 Dose effect on cell apoptosis induced by DCVC co-treated with DPPD. SMMC-7721 hepatocellular carcinoma cells were treated with 0.02 mmol/L DPPD and various DCVC concentration for 6 h, then harvested for flow cytometry assay to estimate apoptosis. A: Absent both DCVC and DPPD; B: absent DCVC; C: DCVC (0.005 mmol/L); D: DCVC (0.01 mmol/L); E: DCVC (0.02 mmol/L); F: DCVC (0.05 mmol/L); G: DCVC (0.1 mmol/L); H: DCVC (0.2 mmol/L).
