Figure 5. Angiogenesis imaging and capillary staining.

Figure 5

(A) Coronal single‐photon emission computed tomography/x‐ray computed tomography scV/Tc scans from a pig treated with IgG on left and pig treated with anti–receptor for advanced glycation end products antibody (CR‐3) on the right. The yellow arrow points to the occluder. The red line outlines the gastrocnemius muscle. The green arrow points to the greater uptake of scV/Tc in gastrocnemius in the CR‐3 treated pig compared with IgG treated pig. (B) Bars represent mean±SD for ratios of percentage injected dose (%ID) of uptake of scV/Tc for the IgG treated pigs (orange bar) and CR‐3 treated pigs (gray bar). (C) Lectin staining for capillaries shows more abundant capillaries in CR‐3 treated (right) compared with IgG (left). (D) Bars represent mean±SD quantitative lectin staining. (E) Immunostaining for vascular endothelial growth factor A (VEGFA) showing greater capillary staining in muscle from CR‐3 treated pigs. (F) Bars represent mean±SD for quantitative VEGFA staining.
