Immunohistochemical staining of VEGF-A, bFGF, TGF-β, MCP-1, TSP-1 in tissues. Representative sections showing immunohistochemical staining of VEGF-A (A, B, and C), bFGF (D, E, and F), TGF-β (G, H, and I), MCP-1 (J, K, and L), TSP-1 (M, N, and O) in healthy controls (A, D, G, J, and M), adjacent non-tumor tissues (B, E, H, K, and N) and tumor tissues (C, F, I, L, and O). The signals were detected by DAB staining.
