    Notes: Summary A medium conditioned by rat embryo cultures (RCM) promoted the adhesion of liver cells from human fetuses to plastic dish. Colonies were also formed in primary cultures of the same cells in the presence of RCM. The majority of the colonies formed were composed of large polygonal cells with a few colonies composed of both clear epithelial-like cells and fibroblast-like cells. RCM was superior to the rat embryo feeder layer for promotion of colony formation of cells. A number of colonies were formed from fetal human livers when a conditioned medium from human hepatoma cells (HCM) was used, but most of the colonies formed were composed of fibroblast-like cells. The cells derived from the polygonal cell colonies, which were formed in the presence of RCM, have been passaged four times and they are still growing with albumin-producing capacity. The effect of RCM was reduced by various physico-chemical treatments.

    Notes: Summary Alpha-fetoprotein (AFP)-producing capacity and some other properties of human hepatoma cell lines treated with chemotherapeutic agents, such as mitomycin C, Adriamycin, cisplatinum, and 5-fluorouracil were investigated. In the case of hepatoma cells that can be grown in culture following treatment with chemotherapeutic agents, their AFP-producing capacity was almost equal to that of untreated control cells with a few exceptions. On the other hand, in the case of similarly treated hepatoma cells that cannot be grown in culture, their AFP-producing capacity was quite different from that of untreated control cells. Under these conditions chromosomal and morphological aberrations were also observed in the treated cells. The present study shows that AFP-producing capacity of hepatoma cells can be changed by chemotherapeutic agents, probably through chromosomal mutation.

    Notes: Summary Collagenase-liver-perfusion technique, currently used with adult rat liver, was applied to isolation of hepatocytes from suckling rat liver. The total hepatocyte numbers isolated from suckling rats by collagenase-liverperfusion technique were 9-fold higher than those by non-perfusion technique. The yield and viability of isolated hepatocytes from suckling rats were 18.1 × 107 cells per gram liver and 95%, respectively. The cell yield per gram liver and viability from suckling rats were 185% and 112% of those from adult ones, respectively. In comparison with adult rat hepatocytes, suckling rat hepatocytes were smaller and more homogeneous. The percentage (3.1%) of binucleate cells in the hepatocytes isolated from suckling rats was about one tenth of that (30.7%) in the hepatocytes isolated from adult rats. The isolated suckling rat hepatocytes had higher tyrosine aminotransferase (TAT) and glucose-6-phosphate (G6Pase) activities than adult ones. Suckling and adult rat hepatocytes were transferred to primary culture to compare their cell number kinetics and functional longevities. The functional longevities of those hepatocytes were assessed by their capacity to secrete albumin and alpha-fetoprotein (AFP) into the culture medium and to express TAT and G6Pase activities up to day 6 of primary culture.
