title: Xenogeneic transfer of fetal liver and adult bone marrow-derived haemopoietic cells in rodents: changes in spleen colony differentials with increased doses of cells.
abstract: The effect of very high haemopoietic cell doses were investigated on the composition of splenic cell colonies/clusters in irradiated animals under xenogeneic circumstances. Differential cluster/colony counts from serial histological sections of the spleen were investigated before, and 9-12 days after transplantation of fetal liver- or adult bone marrow-derived haemopoietic cells following 5.0 to 8.5 Gy total body irradiation. Syngeneic as well as xenogeneic (mouse to rat and rat to mouse) transplantations were carried out. Cluster/colony differentials changed with the increase of the injected cell mass from 10(5) to 10(6) and 10(7) or more, i.e. the overwhelming erythroid pattern became trilinear even with xenogeneic transplants.
