| pubmed-article:8671717 | pubmed:abstractText | The choice of harvest time in in vitro cytogenetics assays is a critical factor in determining the sensitivity of the assay for detecting clastogenic potential. As yet there is no harmonization of regulatory requirements in this aspect. It has been suggested that the use of extended harvest times can improve the sensitivity of detecting some chemicals which either induce cell cycle delay or produce lesions which induce chromosome aberrations at divisions subsequent to the first post-treatment mitosis. The incidence of such chemicals encountered in the routine testing of chemicals for regulatory submissions is not known. Therefore a large database of 550 chemicals tested in nine laboratories using standard regulatory protocols, including a late harvest time, was assessed for the incidence of chemicals uniquely positive only at a delayed harvest time. The number of such chemicals was very low ( < 0.2%) and the chromosome damage induced by these chemicals may not result from direct genotoxic mechanisms. Based on these data it is recommended that there is no need to include an extended harvest time in in vitro cytogenetics assays except where it might help to resolve an equivocal result. | lld:pubmed |
