Figure 3.

Immunohistochemical staining of PABPC4 (A) and FAM50A (B) antigens in cells of lymphocytic infiltrate of medullary breast carcinoma. Both antigens showed more intensive staining of immune cells compared with cancer cells. Positive cytoplasmic PABPC4 staining was detected only in a part of immune cells. FAM50A showed preferentially nuclear staining in immune cells. Positively stained cells are indicated by arrows. C – cancer cells, L – lymphocytic infiltrate. Magnification 400x
