Overlapping proteins indicate those proteins identified as correlated significantly by both Pearson linear regression and partial least squares regression

ANG-1 angiopoietin-1, BMP-2 bone morphogenetic protein 2, EGF epidermal growth factor, FGF-1 fibroblast growth factor 1, IL-6 interleukin 6, IL-8 interleukin 8, IL-15 interleukin 15, MCP-1 monocyte chemoattractant protein 1, RANTES regulated upon activation, normally T-expressed, and presumably secreted, also known as CC-motif chemokine ligand 5, THPO thrombopoieitin, VEGF-A vascular endothelial growth factor A.
