WIF1 and β-catenin staining images of human cervical tissues by IHC. ((a), (c)) Positive cytoplasmic staining of WIF1 was observed in both NCE and CIN. ((b), (d)) Positive membranous staining with no cytoplasmic/nuclear staining of β-catenin was observed in both NCE and CIN. (e) Positive nuclear staining without membranous/cytoplasmic staining of WIF1 was observed in CC. (f) Positive cytoplasmic staining of β-catenin was observed in CC. Magnification: ×200 (hematoxylin counterstained). Insets are magnified images from selected areas (small squares).
