(A) Sample description. The TMS FACS data was collected from 16 C57BL/6JN mice (10 males, 6 females) with ages ranging from 3 months (20-year-old human equivalent) to 24 months (70-year-old human …

(A) Using only male mice. (B) Using only 3 m and 18 m male mice. (C) Using only female mice, which are either 3 m or 18 m. We can see that most tissue-cell types in panel A have significantly more …
(A) Using all mice. (B) Using only male mice. (C) Using only female mice. We can see that there are more downregulated aging-related genes in all three panels. The comparison between panels B and C …
For each aging-related tissue-cell-gene tuple (defined as the gene significantly related to aging in a tissue-cell type), we computed its aging trajectory by first computing the mean expression of …
We computed and clustered the aging trajectories for genes in the TMS droplet data similar to Figure 1—figure supplement 4. As shown in panel A, according to the elbow method there are k = 3 …
The bar plots show the correlation between age coefficients estimated with and without CDR correction, across all the genes, for each tissue-cell type separately. The average correlation, across all …
(A) Tissue-cell level aging-related genes with color indicating the number of the genes. The x-axis shows the weighted proportion of tissue-cell types (out of all 76 tissue-cell types) where the …
Source data for Figure 2.
The figure axes are the same as Figure 2A. We observe significant overlap between the FACS aging-related genes and all six gene sets, as quantified by Fisher’s exact tests with p-values provided in …
The figure shows, for each tissue-cell type, the proportion of aging-related genes that are also shared by the GenAge human aging genes (blue) and the GenAge mouse aging genes (orange). No …

(A) Top 20 KEGG pathways for the GAGs. (B) Top IPA pathways for the GAGs. The ratio represents the proportion of pathway genes that are also GAGs. (C) Regulation prediction for mTOR pathway by IPA. …
(A) Tissue-cell GAG score effects with 95% confidence intervals. The color represents the functional category of the tissue-cell type. (B and C) Effects of cell functional categories (panel B) and …
Source data for Figure 3.
(A–D) Correlation between the GAG scores computed using different scoring rules. The original GAG score was computed using genes that are significantly related to aging in >50% of weighted …
(A) Histogram of mean log expression of genes used for computing the GAG score. As shown in the figure, there are no genes with very high expression levels, indicating that the GAG score is unlikely …
Most tissue-cell types have lower GAG scores for young cells and higher GAG scores for old cells. However, as shown by the GAG score distribution plots in panel A, we found four tissue-cell types …
(A) TMS droplet data. (B) Data (Kimmel et al., 2019). (C) The bulk data (Schaum et al., 2020). (D) Data (Kowalczyk et al., 2015).
(A) Number of discoveries for each tissue. The left panels show the number of aging genes (discoveries) for each tissue, broken down into the number of upregulated genes (orange), and the number of …
