title: Correlation of bacterial mutagenicity and hamster cell transformation with tumorigenicity induced by 2,4-toluenediamine.
abstract: In the presence of rat liver microsome enzymes, 2,4-toluenediamine (TDA) was mutagenic for several tester strains of Salmonella typhimurium. TDA induced morphological transformation in an in vitro carcinogenesis system using secondary culture target cells prepared from cryopreserved primary Syrian hamster embryo cells. These results now correlate bacterial mutagenicity and in vitro morphological transformation with the reported tumorigenicity of this compound.
