VEGFA and fibrosis: For the Human Fibrosis array (Additional file 1: Table S1), in the gels of patient cells with vehicle media compared to those of control cells with vehicle media, 3 genes were upregulated, e.g., collagen (COL) 3A1, and thrombospondins (THBS) 1 and 2, and 17 were down-regulated, e.g., platelet-derived growth factor (PDGF), vascular endothelial growth factor (VEGF), integrins (ITG) A3 and B6, and matrix metallopeptidase (MMP) 1 (Fig. 3a).
