Figure 3. Fluorescence microscopy with red fluorescent antibody for integrin αv in rat RPE-choroid. Non-treated retinas show positive antibody binding for integrin αv around the normal vessels (red arrows) and in the RPE (orange arrows). The yellow arrows show positive red antibody binding for integrin αv between the subretinal and suprachoroidal spaces after laser treatment. The white arrow indicates isolectin binding in green macrophages and microglial and endothelial cells and near the new tubular structures (green arrows). The blue arrows show colocalization of red integrin αv with green macrophages and microglial and endothelial cells. Scale bar = 100 μm.
