| Abstract: | Immunohistochemical staining of cell lines derived from human liver tumours showed that five cell lines derived from hepatocellular carcinoma (HCC) and hepatoblastoma were stained positively with monoclonal keratin antibodies, CK-5 (Ker-18-specific) and KL-1 (broad specificity), but not with CK-7 (Ker-7-specific). On the other hand, four carcinoma cell lines derived from the biliary system were stained positively with not only CK-5 and KL-1, but also CK-7. |
