Effect of anti-Fas MoAbs (CH-11 and ZB4) on HUVEC apoptosis. After the HUVECs were stimulated with or without TNF-α (100 ng/ml) for 5 h, the cells were cultured in the presence and absence of anti-Fas MoAbs (500 ng/ml of CH-11 and 200 ng/ml of ZB4) for 1 h, followed by the incubation with IVIG (20 mg/ml) for 24 h. The percentage of cells with hypodiploid DNA was expressed as the means of the samples ± SD from five experiments. Control indicates no treatment of anti-Fas MoAbs. *P < 0·05 versus control in the same group. □ Control;
CH-11; ■ ZB4.
