CD96 is a leukemic stem cell-specific marker in human acute myeloid leukemia.

ABSTRACT: Permanent cure of acute myeloid leukemia (AML) by chemotherapy alone remains elusive for most patients because of the inability to effectively eradicate leukemic stem cells (LSCs), the self-renewing component of the leukemia. To develop therapies that effectively target LSC, one potential strategy is to identify cell surface markers that can distinguish LSC from normal hematopoietic stem cells (HSCs). In this study, we employ a signal sequence trap strategy to isolate cell surface molecules expressed on human AML-LSC and find that CD96, which is a member of the Ig gene superfamily, is a promising candidate as an LSC-specific antigen. FACS analysis demonstrates that CD96 is expressed on the majority of CD34(+)CD38(-) AML cells in many cases (74.0 +/- 25.3% in 19 of 29 cases), whereas only a
