this paper describes the rare cytoplasmic transmission of defective simian virus 40 ( sv40 ) viral dna from enucleated cells ( i.e. , cytoplasts ) of the sv40-transformed mouse cell line svt2 ( chloramphenicol-resistant ) into cybrid cells formed by fusion of these cytoplasts with balb/c 3t3 cells ( thymidine kinase-deficient ) .
