(A) In normal urothelial cells, strong or moderate 4N1K expression was detected in all specimens. (B) In cancer tissues, some specimens demonstrated strong or moderate 4N1K expression. This figure was a representative example of strongly stained cancer cells (C) A representative image of weakly stained tissues for 4N1K peptide. All sections were counterstained in hematoxylin (Magnification: ×400; Bar means 10 μm)
