Fig. 2. expression of vascular endothelial growth factor (VEGF) receptors during human dendritic cell differentiation and subsequent maturation in the presence of prostaglandin E2 + tumour necrosis factor alpha (PG-TNF) or Bacillus Calmette-Guérin (BCG). Human peripheral blood monocytes were cultured and differentiated as described in the legend to Fig. 1. The mean frequencies and standard deviation (n = 5 independent experiments) of dendritic cell expressing VEGFR1 (A), VEGFR2 (B) or VEGFR3 (C) are shown in the graphs accompanied by the mean values of mean fluorescence intensities (MFI). Significant differences (p < 0.05) are indicated by an asterisk.
