Fig. 4From: MAST: a flexible statistical framework for assessing transcriptional changes and characterizing heterogeneity in single-cell RNA sequencing dataGene–gene correlation (Pearson’s rho) of model residuals in non-stimulated (a) and stimulated (b) cells, and a principal components analysis biplot of model residuals (c) on both populations using the top 50 marginally differentially expressed genes. As marginal changes in the genes attributable to stimulation and CDR have been removed, clustering of subpopulations in (c) indicates co-expression of the indicated genes on a cellular basis.
