Immunohistochemical analysis of cystatin M expression in matched primary breast tumors and lymph node metastases. Representative examples of matched pairs of primary breast tumors (top panel) and lymph node metastasis (bottom panel) are shown. Primary breast tumor P1 shows reduced cystatin M immunostaining compared to its matched lymph node P1N1. Primary breast tumor P3 and lymph node metastasis P3N1 both show positive staining for cystatin M. Primary breast tumor P4 shows positive staining for cystatin M compared to its matched lymph node metastasis P4N1. Primary breast tumor P5 and lymph node metastasis P5N1 both show negative staining for cystatin M. (Original objective lens magnification 10x).
