Immunofluorescent staining for endothelial protein CD31. Representative confocal images showing CD31 (red) and green fluorescent protein (GFP) staining at day 14 in a wound after treatment with recombinant adenovirus encoding angiopoietin-1 (Ad-Ang1), mesenchymal stem cells (MSCs) and angiopoietin-1 gene-modified bone marrow mesenchymal stem cells (Ang1-MSCs). Nuclei were stained blue with Hoechst (blue). GFP and CD31 double-positive cells (yellow) were only found in Ang1-MSC-treated wounds. Scale bar = 50 μm.
