Flow cytometry confirmed that Cd155 and Cd47 were strongly expressed in cKIT+ leukemia progenitors from Vav-cre Tet2fl/flTp53fl/fl AML mice compared with cells from Vav-cre Tet2fl/fl, Vav-cre Tp53fl/fl, or WT mice (Figure 9, A–C, and Supplemental Figure 11A). The gene discussed is PVR; the disease is acute myeloid leukemia.
