[Formation of hematopoietic colonies of the donor type in the bone marrow of irradiated chickens after transplantation of the cells of the yolk sac and hindlimb of the quail embryo].
The ability of yolk sac and primary bone marrow cells of the quail to form hemopoietic colonies at 6 hours of incubation (i. e. before establishment of circulation) was studied in the bone marrow of 3-week sublethally irradiated chickens. The experiments were based on the possibility of differentiating between quail and chicken cells from the natural cell marker (Pheulgen-positive nucleolus). The number of hemopoietic colonies produced by cells transplanted from the primary bone marrow was three times greater than that consequent on transplantation of yolk sac cells. With the given dose of irradiation the bone marrow shows about 75% exogenous (quail) and 25% endogenous (chicken) hemopoietic colonies.
