Immunostaining of CD44v6 with mAb VFF18 in formalin-fixed specimens from patients with invasive ductal breast cancer. A In addition to distinct membrane staining, cytoplasmic staining can also be observed in part of the tumour cells. Note the heterogeneous staining of the tumour cells with about 30% of cells displaying no reactivity with the antibody. B CD44v6 expression in normal skin keratinocytes adjacent to the tumour. Counter stain haematoxylin, original magnification x200
