Now , by competition experiments with a panel of different unlabelled cells we show that the VCSA expressed on RSV - transformed hamster fibroblasts is a complex of at least three distinct antigenic specificities : ( 1 ) one expressed on all RSV - transformed fibroblasts , regardless their species and the subgroup or strain of the transforming virus ; ( 2 ) one cross - reacting with a cell - surface antigen ( CSA ) expressed at various degrees on untransformed avian fibroblasts , but not on mammalian fibroblasts ; ( 3 ) one species - specific , present only on RSV - transformed hamster fibroblasts .
