the present study shows that the bone marrow subset reactive with both rfb-1 and rfb-hla-dr contains all the cells that give rise to mixed hematopoietic colonies ( derived from cfu-gemm ; a pluripotent human progenitor cell ) as well as to megakaryocytic ( megakaryocyte-cfu-derived ) and erythropoietic ( derived from erythroid burst-forming units , bfu-e ) colonies , as shown by fluorescence-activated cell sorting and complement-mediated cytotoxicity .
