The EV-O-derived cell line DF-1 supports the efficient replication of avian leukosis-sarcoma viruses and vectors.
The lack of a well-behaved permanent, adherent, nontransformed chicken cell line has made some experiments with avian leukosis-sarcoma viruses (ASLV) and vectors considerably more difficult. The EV-O-derived line, DF-1, supports the efficient replication of subgroups (A), (B), and (C) ASLV, as well as amphotrophic murine leukemia virus and an ASLV-derived vector that has its env gene derived from the env gene from an amphotrophic murine leukemia virus. The cell line responds appropriately to the expression of a transforming oncogene (v-myc) to a growth suppressor gene [p21(waf1)] and can be sorted (using FACS) if infected by an ASLV vector that expresses GFP.
