Transformation of chick fibroblast cultures with avian myeloblastosis virus

Abstract
Cellular transformation was induced with avian myeloblastosis virus strain BAI‐A (standard AMV) and with a strain of AMV containing subgroup B only. Cultures of muscle tissues from either chick embryo or day old chicks were used for this study. Results were similar in C/O and C/A cells. Leukemogenic virus was continuously produced by these transformed cultures.
