Figure 5. CD26⁻ SC population in CP CML is defined by low FSC.

Upper row shows FSC histograms (dashed line) for the entire SC population (CD45⁺ 34⁺ 38⁻), with the CD26⁻ SC population highlighted as a solid line (A). The CD26⁻ SC populations were gated from CD26 SC expression histograms in the lower row of identical patients (B). Pt. no. – patient number.
