The effect of interleukin (IL)-9 on vascular endothelial growth factor (VEGF) secretion in human keratinocytes. The concentration of VEGF in the control, 10 ng/ml IL-9 and 20 ng/ml IL-9 groups was 189·79 ± 10·94 pg/ml, 275·83 ± 18·58 pg/ml and 322·06 ± 32·34 pg/ml, respectively (24 h); 279·84 ± 14·34 pg/ml, 388·39 ± 19·31 pg/ml, 425·32 ± 30·75 pg/ml, respectively (48 h). The concentrations of VEGF were elevated significantly in 10 ng/ml and 20 ng/ml IL-9 groups compared with the control group at 24 h and 48 h, respectively (*P < 0·01). The concentrations of VEGF were elevated significantly in 20 ng/ml IL-9 groups compared with the 10 ng/ml IL-9 groups at 24 h and 48 h, respectively (#P < 0·01). There were significant differences between 24 h and 48 h in the 10 ng/ml IL-9 groups (♦P < 0·01) as well as at 20 ng/ml IL-9 groups (▴P < 0·01).
