Relationships of Alpha-SMA-Positive Fibroblasts and SDF-1-Positive Tumor Cells with Neoangiogenesis in Nasopharyngeal Carcinoma

<table>The expression of <i>α</i>-SMA in nasopharyngeal tissues. Formalin-fixed and paraffin-embedded biopsies of nasopharyngeal tissues were obtained from chronic nasopharyngitis (inflammation) and NPC tissues. The expression of <i>α</i>-SMA was assessed by immunoperoxidase staining (brown). Arrows indicate <i>α</i>-SMA-positive cells. The red dotted line is border between cancer nest and stromal area. Original magnification is 100x (upper) and the insets are enlarged in the lower panels (200x). Scale bar represents 50 <i>μ</i>m. Ep: epithelium. Ca: cancer cells.</table>
