Figure 1.

Comparison of the localizations of CD34, neural/glial antigen 2 (NG2), platelet-derived growth factor receptor (PDGFR)-β, S100 and PDGFR-α in the endoneurium. Transverse frozen section of a normal rat sciatic nerve (double immunofluorescence, as described in the Materials & Methods). (A) Co-expression of CD34 (red) and NG2 (green) in endoneurial fibroblast-like cells (EFLCs), which are scattered between nerve fibers (arrows). (B) Nearly half of EFLCs co-express CD34 (red) and PDGFR-β (green) (arrows). (C) No co-expression of CD34 (red) and S100 (green). (D) No co-expression of CD34 (red) and PDGFR-α (green). Scale bars, 100 µm.
