CD34+CD38– frequency and aberrant marker expression in ALDHbright and ALDHlow compartments in CD34-negative AML.

Detection of immunophenotypic aberrancies in CD34+CD38– ALDHbright and ALDHlow compartments of CD34-negative AML.*Percentage of CD34+CD38– cells within the ALDHbright or ALDHlow compartments.&in the ALDHbright CD34+CD38– compartment, the aberrant marker expression, both CLL-1 and lineage markers, is indicative for the neoplastic character of the cells.‡data in between parenthesis represent number of cells in cases where there is low compartment in CD34-negative AML cases is essentially devoid of CD34+CD38– stem cells.
