Summary of mRNAs and proteins and coherently and noncoherently expressed mRNA-protein pairs of each cell type. A: the numbers of mRNA signatures, protein signatures and conserved signatures identified for epithelial, endothelial, immune, and mesenchymal cells. B: heatmap depicts z-score-normalized transcriptomic and proteomic profiling of epithelial (Epi), endothelial (Endo), immune and mesenchymal (Mes) cells using common signatures.
