Fig. 5. Decoupling of blast phenotype and genotype in response to FLT3 inhibitor therapy.

Fig. 5

a Fishplot showing observed fraction of cells with distinct genetic mutations for each sampled timepoint. The co-occurrence of the three mutations in the single-cell data is consistent with a linear model of mutation accumulation. b UMAP embedding of all cells based on measured antibody signal. The cells segregate into six distinct phenotypic clusters with multiple blast compartments. c Average expression of each cell cluster for a selection of markers. d Top row: Same UMAP embedding as in b given as grey outline. For each sampled timepoint, observed cells are plotted and colored according to the detected genotype. Blasts distribute among multiple phenotypic compartments in the final timepoint following FLT3 inhibitor treatment. Middle row: kernel density plot of the CD33 antibody signal resolved by timepoint and genotype. Cells from genotypic compartments with less than ten cells per timepoint are not plotted. Bottom row: bar chart depicting genotypic composition of each phenotypic cluster in b resolved by timepoint. Source data are provided as a Source data file.
