Visualization of micronuclei induction by chemicals and drugs enables measurement of possible compound genotoxicity. A loss of entire chromosome or a fragment of chromosome can lead to formation of micronuclei (MNi). The in vitro micronucleus assay can be conducted using nuclear dyes with high-content imaging platforms. This chapter describes the cytochalasin block method of measuring micronuclei in CHO-K1 cell lines.
