There are three types of anti-MAM immuno-staining patterns observed: (1) cytoplasmic stain pattern (Figure 3A and 3C); (2) membrane stain pattern showed at the surface of some breast cancer cells (Figure 3B); and (3) luminary stain pattern showed at the luminary surface of some benign mammary glands (Figure 3D). This evidence concerns the gene SGCG and breast cancer.
