Figure 3 Impairment of Chemotaxis of EPCs and Increased Chemokinesis
The EPCs isolated from blood up to 24 h after SHS exposure showed abolished chemotactic response to a VEGF (50 ng/ml); no effect was seen after exposure to clean air in the chamber. Random cell movement was significantly increased at 2.5 h and 24 h. Symbols are mean ± SEM. *p < 0.05 versus baseline of same day (exposure condition). #p < 0.05 comparing SHS and clean air at the same time. VEGF = vascular endothelial growth factor; other abbreviations as in Figures 1 and 2.
