CD34 and acute myeloid leukemia: Interestingly, we detected high puromycin levels, displayed as median fluorescence intensity (MFI), in CD34+ cells in comparison to paired CD3+ cells after vehicle (Control, Co) or oligomycin treatment (O) (p < 0.0001, respectively; Fig. 2a), indicating higher protein synthesis and metabolism in the CD34+ AML cell fraction.
