Violin plot for mitochondrial gene transcripts (%mtRNA), cardiac marker (Tnnt2), and pacemaker marker (Hcn4) for identified cell clusters. A In iSABs, most pacemaker cells exceed 5% mtRNA; B almost all cells of the SAN cluster of murine sinoatrial node tissue exceed 5% mtRNA. Results obtained from a data reanalysis of Goodyer et al. [1]
