title: Induction of SCEs by some pyrrolizidine alkaloids in V79 Chinese hamster cells co-cultured with chick embryo hepatocytes.
abstract: Genotoxicity of heliotrine, monocrotaline, seneciphylline and senkirkine was studied with the sister-chromatid exchange assay in V79 Chinese hamster cells. Exposure to these pyrrolizidine alkaloids, in the presence of co-cultured primary chick embryo hepatocytes, resulted in a high induction of SCEs. It was also shown for heliotrine that co-cultivation with chick embryo hepatocytes resulted in a much higher response than addition of activated rat-liver homogenate to the test medium.
