Pairwise comparisons of cell types and differentiation stages in scatterplot representation. Pearson correlations between pairwise comparisons using median expression of replicates from all genes for each cell type or differentiation stage (upper right) using median expression of replicates. (Lower left) The scatterplot data of log 2 counts per million. (Middle) Histograms of the log counts per million for each sample. The axes label represent the log counts per million for the scatter and histogram plots. The y-axis for the histogram plots is scaled by the maximum y value. Circles indicate the level of similarity/dissimilarity between HSPCs and proerythroblasts is nearly identical to the level of similarity/dissimilarity between proerythroblasts and orthochromatic (Ortho) erythroblasts.
