Effect of stimulation of B7-H6 on tumor cell apoptosis. Apoptosis was evaluated using Annexin V-FITC/7-AAD staining and analyzed by flow cytometry. (a) HeLa cells and (b) SiHa cells were stimulated with different concentrations of sNKp30 (20, 40, 80 ng/mL) and were compared with the basal treatment (NKp30 0 ng/mL). In (c) and (d): graphical results of three independent experiments with HeLa and SiHa cells, respectively; *p < 0.05 (analysis of variance)
