Localization of NPY Y₂ receptor on the newly formed blood vessels. Histological sections of NPY-implanted (A–D), FGF-2-implanted (E–H), and VEGF-implanted (I–L) corneas were incubated with an anti-Y₁ (A, E, and I), an anti-Y₂ (B, F, and J), an anti-Y₄ (C, G, and K), or an anti-Y₅ (D, H, and L) receptor antibody and stained with a peroxidase-conjugated secondary antibody. Endothelial cells of corneal microvessels were immunoreactive as indicated by arrows (B, F, and J).
