Figure 7.
In metastatic melanomas, VEGF staining, but not VEGFxxxb staining is upregulated. Although VEGF staining was clearly seen in peritumoral epidermis, and horizontal growth phase (HGP; supra) and vertical growth phase (VGP; intra), this was in contrast to VEGFxxxb staining in serial sections. In nonmetastatic melanomas however, VEGF staining was similar to VEGFxxxb staining in all three tissue types. (A–F) Metastatic melanoma, (G–L) nonmetastatic melanoma, (A–C and G–I) VEGF staining, (D–F and J–L) VEGFxxxb staining, (A, D, G and J) normal skin, (B, E, H and K) HGP(supratumoral), (C, F, I and L) VGP (intratumoral).
