Extended Data Fig. 8: Data quality of PBMCs from human aging cohort.

a. The violin plot shows the distribution of gene numbers per cell across donors in the cohort. The number of cells per donor showing in (b). Box plots show interquartile range with the median marked. The whiskers extend up to 1.5 times the interquartile range, the outliers are not displayed. b. The bar plot shows the number of cells per donor in the cohort. c. Aging-associated cells are displayed in the UMAP plot, with colors indicating the strength of the association. Positive and negative numbers represent positive and negative associations, respectively. d. Imputed CD31 protein expression is shown across CD4 Naïve sub-clusters. The imputation is from the CITE-seq PBMC atlas. e. The gene expression level of PECAM1 across CD4 Naïve sub-clusters is displayed. The PECAM1 gene encodes the CD31 protein. f. The percentage of BCR and TCR detection in scVDJ-seq is shown in this cohort.
