Impact of Nuclear Interleukin-1 Alpha and EGFR Expression on Recurrence and Survival Outcomes in Oral Squamous Cell Carcinomas

Figure 1

Representative examples of nuclear and cytoplasmic IL-1α immunostaining in OSCC and expression scores. (a) IL-1α expression in the nuclei; (b) IL-1α expression in the cytoplasm; and (c) IL-1α in both the nuclei and cytoplasm. (d) negative nuclear and cytoplasmic IL-1α expression; (e) moderate nuclear and negative cytoplasmic IL-1α expression; (f) negative nuclear and moderate cytoplasmic IL-1α expression; (g) moderate nuclear and cytoplasmic IL-1α expression; (h) moderate nuclear and strong cytoplasmic IL-1α expression; (i) strong nuclear and moderate cytoplasmic IL-1α expression. N: nuclear; C: cytoplasmic.
