| Abstract: | A study of the number of stem cells in splenic colonies and of marked chromosomes in the progeny of the stem cells that recirculating colony-forming units from peripheral blood or from a focus of ectopic hematopoiesis have reduced self-support potential compared with settling (from bone marrow) colony-forming units. The powers of differentiation of the two subpopulations of stem cells were identical.Laboratory of Bone Marrow Culture and Transplantation, Central Institute of Hematology and Blood Transfusion, Moscow.
