title: Evaluations of wasted mouse fibroblasts and SV-40 transformed human fibroblasts as models of ataxia telangiectasia in vitro.
abstract: Fibroblast cultures from wasted mice have been derived and the responses of these cultures to bleomycin treatment or gamma-irradiation have been examined. No differences were observed between wasted fibroblasts and littermate controls in the post-treatment inhibition of DNA replication. In contrast, a human SV-40 transformed ataxia telangiectasia fibroblast line mimicked the abnormal response of primary ataxia telangiectasia fibroblasts to gamma-rays or bleomycin and thus appears to be a useful in vitro model of ataxia telangiectasia.
