Transforming ability of avian defective leukemia viruses in early embryogenesis.
The response to infection of chicken hemopoietic cells derived from the early stages of embryogenesis by avian myeloblastosis virus (AMV) and avian erythroblastosis virus (AEV) was investigated. It was found that erythroid progenitor cells were present in the blastoderm at a higher frequency than that of myeloid progenitor cells. These results correlate with the observation that target cells for AEV were found to be more numerous than those for AMV. Therefore, blastoderm cells are of potential value in understanding the mechanisms of oncogenesis at the level of the target cells.
