Figure 1From: Molecular and epigenetic analysis of the fragile histidine triad tumour suppressor gene in equine sarcoidsExpression of FHIT in equine sarcoids and normal skin. A) FHIT protein is not expressed in neoplastic fibroblasts. Streptavidin-biotin peroxidase method. Mayer's haematoxylin nuclear counterstaining. × 120. B) Neoplastic fibroblasts do not express FHIT. Streptavidin-biotin peroxidase method. Mayer's haematoxylin nuclear counterstaining. × 120. C) FHIT is expressed in normal skin. Normal fibroblast display cytoplasmic immunosignal. Normal blood vessels and sweat glands also stain. Streptavidin-biotin peroxidase method. Mayer's haematoxylin nuclear counterstaining. × 240.Back to article page
