<p>(A -H) Paraffinembedded tissue sections were stained with antibodies for PFTK1 and Ki-67 and counterstained with hematoxylin. (A,E) negative staining of PFTK1, Ki-67 in adjacent normal tissues (×200); (B,F) weak staining of PFTK1, Ki-67 in well differentiated gastric cancer tissues; (C,G) moderate staining of PFTK1, Ki-67 in moderate differentiated gastric cancer tissues; (D,H) strong staining of PFTK1, Ki-67 in poor differentiated gastric cancer tissues, amplification (×100, ×400).
