Figure 1From: Elevated IGFIR expression regulating VEGF and VEGF-C predicts lymph node metastasis in human colorectal cancer Representative examples of immunohistochemical staining of IGFIR, VEGF, and VEGF-C in colorectal cancer. Positive staining is shown in dark brown. Colorectal adenoma tissues were stained with IGFIR (A), VEGF (C), VEGF-C (E) as controls, and colorectal cancer tissues showed strong staining of IGFIR (B), VEGF (D), and VEGF-C (F).
