Figure 5

Representative histological panel of the increased vascularization and inflammatory infiltrated found in the DG group at 12 weeks. The panel reports the Alcian Blue staining (AB). The black arrows show the enlargement and increasing small and large capillary vessels in the transition zone and within the implanted graft (G). The red arrows show the huge inflammatory infiltration both near the vessels and in the transition zone between the native tissue (NT) and the graft (G). The fatty infiltrate (FI) is also detectable. Magnification 100x, scale bar 200 μm.
