JSRV Env induces proliferation and colony formation in A549-Env cells. (A and B) Equal number (1 × 105 cells/well) of A549, A549-Spr and A549-Env cells (A) or BEAS-2B and BEAS-2B-Env cells (B) were allowed to proliferate for four days and live cells were counted every 24 h. (C) A549, A549-Spr and A549-Env cells were cultured in soft agar to assess their anchorage-independent colony formation ability. The colonies were counted and photographed on day 12.
