Figure 1. Fas receptor and FasL immunoreactivity in normal oral mucosa and tobacco-related intraoral squamous cell carcinoma: A. Fas receptor immunoreactivity in normal oral mucosa showing high expression on the cell surface and in the cytoplasm (arrows). B. Faint Fas receptor expression on the cell surface in oral squamous cell carcinoma (arrows). C. Negative FasL immunoreactivity in normal oral mucosa E. High FasL expression in oral squamous cell carcinoma (arrows) (original magnifi cation X400).
