a UMAP projection of individual cells from snRNA-seq and scATAC-seq colored by cell types. Stacked barplots on the right represent the proportions of cell-types from each of the three donors. b UCSC genome browser track plots of chromatin accessibility at selected marker genes across cell types. The bottom part shows the gene track (RefSeq annotation). Shown are two marker genes, TNNT2: cardiomyocyte marker; DCN: fibroblast marker. c Stacked violin plots of marker gene expression (log-normalized expression values) in each cell type.
