Immunohistochemical staining of AFP, p53, CK7 and α-inhibin in tumor cells. Tumor tissues were inflated, fixed in formalin, paraffin-embedded and sectioned for histological analysis. Slides were washed and counterstained with antibodies to AFP, p53, CK7 and α-inhibin using immunohistochemistry staining kits (Maxin BIO, Fu Zhou, China). The results showed that the hepatoid cells were focally positive for AFP (A), positive for p53 (B) and CK7 (C), and α-inhibin (D)) (Original magnification, 200x).
