CD34 and CD38 expression profile on CD34-enriched cells from a typical patient with 5q− syndrome.

CD34-enriched cells from patient no. 4 were stained with CD34-FITC and CD38-PE antibody or isotype control antibody. In this patient, CD34⁺CD38⁺ and CD34⁺CD38⁻ cells represented 91.4% and 8.6% of CD34⁺ cells, respectively. Also shown are the sorting gates for CD34⁺CD38⁺ (R3) and CD34⁺CD38⁻ (R4) cells.
