Typical genomic AP-PCR fingerprinting of synchronous hepatocellular carcinoma (HCC) and regenerative nodules (RNs) in the cirrhotic liver of one patient. Autoradiograms of polyacrylamide gel electrophoresis of ³³P-labelled DNA fragments amplified by arbitrary primers, AR3 (A) and ZF3 (B), showed high polymorphism between different nodules. N, R1-R3, and T1-T7 represent paired PCR reaction samples from non-tumour tissue, three different RNs, and seven different HCC nodules, respectively. Size of bands (in base pairs) is indicated on the right.
