Figure Lengend Snippet: Figure 1. Cell clustering by Amp1200. Lots of SyMSCs (4 donors: S1, S2, S3 and S4), ADSCs (3 donors: A1, A2 and A3), BMSCs (3 donors: B1, B2 and B3), RECs (3 donors: R1, R2 and R3), FBs, iMSCs, WPs, PAECs, T cells, and CD14+ monocytes were clustered by the expression level of genes obtained by Amp1200. The black lines at the top and left showed the results of the clustering. A similar clustering analysis using all 25,193 human genes is shown in Figure S1.

Cells n = 130, 133, 117, 102 for siC normoxia, siA normoxia, siC Reoxy, siA reoxy respectively. d Animal measurements - experimental design: Mice with EC-specific deletion of Atm (EC- Atm -/- ) were created using the strategy described for Fig. , and in the “Methods”. EC- Atm -/- or control mice were exposed to hypoxia (10% oxygen) for 3 weeks followed by 4 weeks of room air (reoxy), or maintained in room air for 7 weeks (normo). Schema created with BioRender.com. e γH2AX immunofluorescence foci in PAEC in control and EC- Atm -/- mice (arrowheads) were quantified in n = 6 mice. Scale bars, 20 μm. The bottom panels show a magnified merged image of the area delineated by the dotted line. Scale bars, 5 μm. In ( a and d ), bars represent mean ± S.E.M.

In ( b and c ) The Bounds of boxes show the 25th and 75th percentiles, the whisker showed to the 10th to 90th percentiles and the centre in the box shows the median. Three independent experiments was performed. P values determined by Kruskal-Wallis ANOVA test with Dunn’s test Source data are provided as a Source Data file.
