Embryonic erythroid cells transformed by avian erythroblastosis virus may proliferate and differentiate

Embryonic chick cells from the primitive streak stage to later stages of the developing embryo were infected with avian erythroblastosis virus (AEV). The data indicate that the greatest number of target cells for AEV was observed in the 12-somite blastoderm and gradually decreased in hemopoietic tis...

Zusammenfassung:Embryonic chick cells from the primitive streak stage to later stages of the developing embryo were infected with avian erythroblastosis virus (AEV). The data indicate that the greatest number of target cells for AEV was observed in the 12-somite blastoderm and gradually decreased in hemopoietic tissues with the development of the embryo. The target cell for AEV is not in the BFU-E compartment, as it is in the adult bone marrow, but is probably recruited within the CFU-M compartment which precedes the BFU-E compartment. Our studies also show that a significant number of transformed colonies derived from embryonic hemopoietic tissues undergo hemoglobinization in contrast with what is observed in transformed colonies of bone marrow. A complete characterization of the embryonic and adult hemoglobin is at present under study.
