Immunohistochemistry of vimentin and Sam68 in the same tumor. (A) Representative image of the broad sheet of tumor cells without vimentin expression at the superficial area. (B) Representative image of the small cords of tumor cells exhibiting positive vimentin expression and higher Sam68 immunoreactivity at the central area. (C) Representative image of the small cords and clusters of tumor cells exhibiting positive vimentin expression and higher Sam68 immunoreactivity at the invasive front. (magnification, ×100; scale bar, 50 µm). Sam68, Src-associated in mitosis 68 kDa.
