(A) CXCR4 positivity in BM HSPC from Flt3-ITD vs Flt3-ITD TET2-KO mice. (B) Transplant scheme for CXCL12-GFP mice. (C) Frequencies of endothelial cells, PAC, and CAR cells within CD45-Ter119-population (left) and percentage GFP (CXCL12) positivity in endothelial, PAC, and CAR cell populations (right) in CXCL12-GFP mice transplanted with WT vs. Flt3-ITD TET2-KO AML cells. Significance values: *p<0.05; **p<0.01; ***p<0.001; ****p<0.0001; ns, not significant. Results represent mean ± SEM of multiple replicates.
