SOX2 expression in primary HNSCC specimens. (A) Immunohistochemical analysis of expression of SOX2 from primary HNSCC specimens (magnification: × 200 and × 400). (B) The disease-specific survival rate according to SOX2 expression using the Kaplan survival curve. (C) Immunofluorescent images showing colocalization of SOX2 (green) with CD44 (red) on an HNSCC specimen. Nuclei were stained with DAPI (blue). Bar, 20 μm.
