<p>The establishment of permanent cell line that can produce an alpha-fetoprotein has made tissue culture a powerful tool for the study of alpha-fetoprotein. For this reason, the hepatoma cells of rat ascites hepatoma AH70B were cultured in vitro and some biological characters of the isolated six clones examined. The cultured cells were morphologically epithelial and the mode of chromosome number in hypotetraploid range, and possessed tumorigenicity. The cells secreted alpha-fetoprotein at the high level and a few components of serum proteins in the culture medium for more than one year. Alpha-Fetoprotein was also detected in cytoplasm by fluorescent antibody technique. The examined character was little different among the six colonial clones. From the present cloning procedure, it was suggested that the cultured cells derived from a single cell were secreting alpha-fetoprotein and several components of serum proteins together.</p>
