Proportion of ncMono within the leukemia-associated myeloid cell-enriched compartment of patient samples. (A) Mann-Whitney U test demonstrating a significantly increased proportion of ncMono within the leukemia-associated myeloid compartment (CD45⁺CD19^–CD10^–CD22^–CD56^–CD3^–CD66b^–) of patient diagnostic BM samples (n = 89) compared with remission BM control samples (n = 4). (B) The proportion of ncMono within the leukemia-associated myeloid compartment of PB samples significantly correlated with that in BM samples using Spearman correlation.
