Abstract
The rodent micronucleus assay has been most widely and frequently used as a representative in vivo assay system to assess mutagenicity of chemicals, regardless of endpoint of mutagenicity. The micronucleus has been developed to assess induction of structural and numerical chromosomal aberrations of target chemical. In this chapter, we describe the standard protocols of the assay using mouse bone marrow and peripheral blood. These methods are basically applicable to other rodents. The methodology of the micronucleus assay is rapidly developing, especially automatic analysis by flow cytometry (see also Chapter 11). Also we have to pay attention to the animal welfare, for example integration into repeat dose toxicity assay, combination of the micronucleus assay and Comet assay, and also omission of concurrent positive control group. Therefore, modification of the standard protocol is necessary for the actual assay on a case-by-case basis.
