Staining of 11β-HSD2 at a 1 : 100 dilution was undertaken using tissue microarrays. The array is shown with (A) and without (B) IHC staining and shows cases of squamous cell carcinoma (n=40), normal skin tissues (n=8) and a positive control (melanoma). Typical aspects of normal (C, E) and cancerous (D, F) samples are reported at × 4 and × 20 magnification. *P<0.05, **P<0.01. A full colour version of this figure is available at the British Journal of Cancer journal online.
