Figure 6From: Serial analysis of gene expression of lobular carcinoma in situ identifies down regulation of claudin 4 and overexpression of matrix metalloproteinase 9Matrix metalloproteinase (MMP) 9 immunohistochemistry (IHC) on separate lobular carcinoma in situ (LCIS) cases a and b. LCIS cells show greater immunoreactivity than strips of undermined normal duct epithelium, which are essentially negative in each case.Back to article page
