Teratogenesis, Carcinogenesis, and Mutagenesis publishes original research on the evaluation and characterization of teratogens, carcinogens, or mutagens. Reports that describe the development of novel experimental techniques for toxicological assessment, or the application of current methods in molecular and cellular biology (including in vitro studies, organ and cell culture, and the use of transgenic animals) are encouraged. Analyses that involve the extrapolation of state-of-the-art methods to human risk assessment are of particular interest. The journal also features critical reviews focused on topics of significant interest to specialists in teratology, cancer biology, and mutation research.
