Extended Data Fig. 1: Quality metrics and marker gene expression in single cells of the normal adult human heart.

a-c, Quality metrics for single-cell RNA-Seq data showing distributions of number of reads per cell (a), alignment rate per cell (b), and number of genes detected per cell (c). d, Gene expression of specific markers in a designated cell type (the mean logTPM of known markers). e, Correlation between detected and expected ERCC (spike-in) RNAs. Each dot represents one spike-in RNA.
