a UMAP representation of the 1,047,793 PBMCs from young and old subjects identified by integrating seven scRNA-seq datasets. b Bar plots showing proportions of the major PBMC subpopulations in each dataset. c Estimation of young (n = 53) and old (n = 50) groups density in the UMAP space. d Estimation of female (n = 44) and male (n = 59) groups density in the UMAP space. e Gene expression of selected marker genes used to identify the major PBMC populations overlaid on the UMAP representation.
