PTPRC and myocardial infarction: Three articles were chosen for further analysis (10, 15, 16): (1) isolating and sequencing CD45+ leukocytes from MI-operated hearts at 4 days after surgery (n = 1,866) or sham-operated hearts (n = 703) (15) (Supplementary Figures 1A,B); (2) isolating all interstitial cells from murine hearts at 3 days (n = 4,067), and 7 days (n = 4,194) after MI or sham (n = 5,977) surgery (10) (Supplementary Figures 1C,D); (3) collecting nonmyocyte cells from the ventricles of mouse hearts (16) under a homeostatic condition (n = 10,542; Supplementary Figure 1E).
