The negative controls of VEGF (a) and TGF-β1 (b) and pre-adsorbtion controls of VEGF (c) and TGF-β1 (d) showed a complete abolishment of specific signals for all antibodies. Positive contols for VEGF (e) and TGF-β1 (f) staining showed a apecific staining partterns in the vascular epithilial cells for VEGF and in the stroma cells for TGF-β1(40x)
