title: Rescue of Rous sarcoma virus (RSV) from RSV-transformed human embryonic cells by cell fusion with chick embryo fibroblasts using lysolecithin.
abstract: Heterokaryon formation and Rous sarcoma virus (RSV)-induction were studied by fusion of RSV-transformed human embryonic cells with chick embryo fibroblasts in the presence of lysolecithin. Heterokaryon formation was observed by autoradiography. RSV-induction was identified by focus formation, electron microscopy and density gradient centrifugation of 3H-uridine-labeled particles. The most effective concentration of lysolecithin for virus induction was 10 mug/10(6) cells/0.1 ml. Efficiency of lysolecithin in virus induction was not less than that of ultraviolet-inactivated Sendai virus (UV-HVJ).
