our results demonstrate heterogeneity among aul patients based on molecular and surface marker analyses and suggest that most aul blast cells are derived from a precursor cell that shares phenotypic and genotypic characteristics of early b cells with certain surface antigens of myeloid cells , in some cases of aul more than one abnormal cell clone or subclone may exist , and the cellular origin , at least of some auls exhibiting t ( 4 ; 11 ) , may be truly b cell lineage committed .
