Although MDS-noEB (n = 6) had a normal profile, MDS-RAEB CD34+ SPCs (n = 6) were similar to AMLs with a major aberrant ki67lowBCL2high population in both CD34+CD38low and CD34+CD38high compartments in all samples, and for some patients (4/6) also in the CD34− compartment (Fig 6C). Here, CD34 is linked to myelodysplastic syndrome.
