Vascular Endothelial Growth Factor and Mesenchymal Stem Cells Revealed Similar Bone Formation to Allograft in a Sheep Model

Figure 2

Illustration of the implant divided into zone 1 (close to the implant) and zone 2 (close to the existing bone). Histological images from the gap in each treatment and control group were stained with toluidine blue O after 12 weeks. A: MSC+VEGF 10 ng/day; B: MSC+VEGF 100 ng/day; C: MSC+VEGF 500 ng/day; D: allograft. These overview pictures were taken with newCAST (Visiopharm, Denmark; lens 4). E: existing bone; G: granula; i: implant; N: new bone.
