We found that the early leukemic stem cell compartment (Lin-/CD33(+)/CD45dim/CD34+CD38-) in all CD34+ AML samples (# 2, 3, 4, 5) was dominated by multilymphoid progenitors (MLP, CD45RA+), whereas in CD34- AML, we also found multipotent progenitors (MPP, CD45RA-CD90-) and hematopoietic stem cells (HSC, CD45RA-CD90+, #7), consistent with published reports (Figure 1B and Supplementary Figure 1B) [34]. Here, CD33 is linked to acute myeloid leukemia.
