when the surface phenotype of the clonogenic leukemic cells was compared to that previously established for normal marrow hemopoietic clonogenic cells , several patterns were seen : ( 1 ) in four of ten cases , the clonogenic cells expressed a phenotype like that of relatively mature normal granulocyte-macrophage colony-forming cells ( late cfu-gm ) or , ( 2 ) in two cases , a phenotype similar to the less mature colony-forming cells ( early cfu-gm or cfu-gemm ) , and ( 3 ) in four cases , a composite phenotype of early and late cfu-gm .
