Establishment and characterization of primary canine hepatocellular carcinoma cell lines producing alpha-fetoprotein.

A primary cultured cell line named CHKS was established from a hepatocellular carcinoma ( HCC) of a dog showing a high level of serum alpha-fetoprotein (AFP). CHKS secreted a 66 KDD AFP into the growth medium regardless of the presence or absence of fetal bovine serum (FBS). Cloning CHKS with limiting dilution produced 4 clones, CHKS-1, -2, -3, and -4, which secreted 826, 471, 70, and less than 10 ng/ml, respectively, of AFP into the culture medium. In culture, these cell lines were similar in morphology and proliferation pattern to epithelial cells and positive to periodic acid-Schiff (PAS) staining. The presence of mRNA for canine albumin was demonstrated by nested PCR. The doubling times of the clone cell lines were 21, 45, 36, and 35 h, saturation densities 34, 18, 22, and 24 x 10(4)/cm(2), and plating efficiencies 18, 45, 46, and 45%, respectively. Chromosome analysis of these cell lines showed near triploidy. These results show that CHKS and its clones have hepatic cell functions and are useful for carcinogenetic and clinical studies of canine HCC.[1]
