Cells incubated with diluents (DMEM) or 5 μg/mL the indicated antibody for 1 h at 37°C were seeded in Boyden chambers for cell migration assays as described in the Material and Method section, in the presence or absence of the indicated effectors. Conditioned medium (CM) of LB6/hSuPAR cells was used as a source of SuPAR. For quantitative analysis of cell migration, the basal value (DMEM) was taken as 100% and all values were reported relative to that. Data are the means ± SD of two independent experiments, performed in duplicate. Statistical significance with P values was calculated against the control DMEM. *Statistical significance with P < .05. **Statistical significance with P < .001.
