the level of beta-interferon mrna detected by in situ hybridization was found to be two to three times higher in tetraploid compared to diploid ht1080 cells , and correlated with beta-interferon activity in that a subclone of tetraploid ht1080 cells secreted two- to fivefold more beta-interferon than a subclone of diploid ht1080 cells .
