121 THE LOCAL MICROENVIRONMENT OF NERVE ALLOGRAFTS AFTER ANGIOGENESIS 6 Figure 5. Density of protein gene product 9.5 (PGP9.5), S100 and CD34 immunoreactivity. (A) Micrographs showing density in mid-distal graft sections from control nerve samples, autograft, allograft and allograft wrapped with a superficial inferior epigastric fascial (SIEF) flap at 12 weeks. Hematoxylin and Eosin (H&E) marker was used as principal stain. Scale bar is set at 100 μm. (B) Qualitative assessment of immunohistochemistry. Density: 0 none, +/- occasional, + sparse, ++ few, +++ moderate, ++++ abundant, assessment described by Ferretti et al. (2003) 23 .
