Analysis of the premyelodysplastic hematopoietic compartment in RUNX1(41-214) animals. (A-F) Percentage of various hematopoietic populations analyzed on flow cytometry. Average and SD values of MigR1 (□; n = 4) and RUNX1(41-214) (■; n = 5) animals are shown. Animals were analyzed 4-6 months after transplantation. Percentage represents values within EGFP⁺/RUNX1(41-214) cells. (G) Representative flow cytometric analysis of the stem/progenitor cell compartment. Lin⁻ indicates EGFP⁺/Lin⁻/IL7Rα⁻; c-Kit⁺, EGFP⁺/Lin⁻/IL7Rα⁻/c-Kit⁺/Sca-1⁻; and KSL, EGFP⁺/Lin⁻/IL7Rα⁻/c-Kit⁺/Sca-1⁺.
