Extended Data Figure 7. Analysis of eGFP+ myocytes in the hearts of Kit+/MCM × R-GFP mice after isoproterenol infusion-induced injury.
a, Schematic diagram showing tamoxifen treatment of Kit+/MCM × R-GFP mice between 7 and 14 weeks of age with isoproterenol (ISO) infusion occurring between weeks 10–14. b, c, Quantitation and imaging of disassociated cardiomyocytes (separate images shown at 2 different magnifications) from the hearts of ISO injured Kit+/MCM × R-GFP mice, which showed rare but definitive cardiomyocyte labeling. *P<0.05 vs R-GFP, 31 eGFP+ cells of 395,302 counted from 2 hearts.
