Glioblastoma cell-secreted angiogenic factors.

A representative scan of the angiogenesis array film was analyzed using ImageJ analysis software. Reference refers to the position on the array as reported on figure 2D. Density represents mean arbitrary values corresponding to pixel intensity for each spot.POS: positive control; Gro-α: growth-regulated oncogene; PlGF: Placenta growth factor; IFN: interferon; RANTES: regulated upon activation, normal T-cell expressed, and secreted; NEG: negative control; IGF: insulin-like growth factor; TGF: transforming growth factor; IL: interleukin; TIMP: tissue inhibitor of metalloproteinases; EGF: epidermal growth factor; ENA-78: epithelial neutrophil-activating peptide 78; MCP-1: monocyte chemotactic protein-1; VEGF: vascular endothelial growth factor; bFGF: basic fibroblast growth factor; PDGF: platelet-derived growth factor.
