Fig. 4From: Bone marrow mesenchymal stem cell-derived endothelial cells increase capillary density and accelerate angiogenesis in mouse hindlimb ischemia modelEffects of uninduced MSCs and induced MSCs on neovascularization at ischemic sites. On day 28 post-surgery, ischemia samples were analyzed to determine endothelial differentiation and neovascularization of transplanted MSCs at the injured sites. Vessel formation was confirmed by immunofluorescence staining for α-SMA (red) (a) and CD31(b). Scale bar = 75um. c In induced MSCs, GFP+ cells co-localized with α-SMA, indicating vasculature formation from transplanted cells. Scale bar = 50umBack to article page
