(A) Heatmap of all differentially expressed genes, clustered by dynamic expression using k-means clustering across hematopoietic progenitor populations (HSC, MPP, CMP, and MEP) and stages of erythropoiesis (MyP, CFU-E, ProE1, ProE2, BasoE, PolyE, OrthoE, and Orth/Ret). Color bar, expression Z score of differentially expressed genes.
(B) Top enriched Gene Ontology biological processes for clusters K4, K5, K6, and K7 of differentially expressed genes. The top five processes are shown for each cluster and their −log10(false discovery rate [FDR]).
