Representative examples of immunohistochemical expression of TAZ and YAP in TNBC patients. a a tumor expressing TAZ in tumor cells and in non-lymphocytic stromal cells. b a tumor expressing TAZ exclusively in cancer cells. c a tumor expressing YAP in tumor cells and in non-lymphocytic stromal cells. d a tumor expressing YAP in tumor cells, but not in non-lymphocytic stromal cells. Black arrows indicate the stromal compartment. The corresponding H&E staining are also showed (e–h). Scale bar = 30 μm
