Cluster analysis of combinding VEGF and sVEGFR2 with significantly correlated cytokines and angiogenic factors. Unsupervised cluster analysis of cytokines and angiogenic factors (CAFs) with significantly correlated with VEGF and sVEGFR2 in patients with gastric cancer. The CAF concentration ratios are depicted by a log-transformed pseudocolor intensity scale. Abbreviation; VEGF, vascular endothelial growth factor; sVEGFR2, soluble vascular endothelial growth factor receptor 2; IL, interleukin; FDR, false discovery rate; SCF, stem cell factor; FGF-basic, fibroblast growth factor 2 basic; PDGF-bb, platelet-derived growth factor beta polypeptide b.
