To obtain a comprehensive appreciation of the temporally and spatially resolved dynamics of cardiac MPCs in infarcted hearts with different regenerative potential, we performed flow cytometry analysis on cardiac CD45+F4/80+ MPCs derived from sham and MI hearts at 3 and 7 days after P1 (regenerative) (P1-MI_3D and P1-MI_7D) and P10 (nonregenerative) (P10-MI_3D and P10-MI_7D) injury. This evidence concerns the gene PTPRC and myocardial infarction.
