Abstract

Adenovirus type 12 (Huie) inoculated into cultures of primary whole rat embryo produced foci of morphologically altered cells. The number and identification of these transformed areas was dependent upon the calcium concentration of the medium; more foci appeared in 0.1 mm than in 1.8 mm calcium. Cell lines derived from these inoculated cultures did not yield infectious virus, and also were similar to cell lines derived from adenovirus type 12-induced tumors with respect to morphology, presence of virus-specific tumor antigen, and oncogenicity. Dose-response curves revealed that transformation of rat embryo cells by adenovirus type 12 followed one-hit kinetics, and that approximately 7 × 105 infectious virus particles were required for one transformation event. Our results indicate that the transformation system described for adenovirus type 12 is reproducible, and that previous difficulties experienced in developing such a system may well be explained by the higher calcium concentration of the tissue culture media used.
