HNSCC tissues compared to non-tumor resection margin present lower PTEN and higher SET scores. (A) Representative micrographs of PTEN immunohistochemical labeling in tumor tissues (N = 6) and their respective resection margin tissues (N = 6). Images were obtained at 20 × magnification using a digital camera (AxioCam MRC, Carl Zeiss, Germany) coupled to a bright field Axiovert 40 light microscope (Carl Zeiss). (B) Micrographs are representative of SET staining in tumor tissues (N = 6) and their resection margin (N = 6). Images were obtained at 20 × magnification using the same equipment reported above in (A).
