F3 and myocardial infarction: Then we performed GSEA analysis and results showed that CD142+ MSCs were related to protein secretions, angiogenesis, myogenesis and hypoxia while CD142- MSCs might be more related to mitotic spindle and G2M Checkpoint (Figure 4E), indicating that CD142+ MSCs exerted secretory and wound-healing bio-functions while CD142- MSCs took in charge of self-renewal function, collaboratively contributing to cardioprotection in post-MI HF.
