Abstract：
:We tested the hypothesis that adipose-derived fresh stromal vascular fraction (SVF) is non-inferior to conventional adipose-derived mesenchymal stem cell (ADMSC) therapy for improving left-ventricular ejection fraction (LVEF) in rat after acute myocardial infarction (AMI). Male-adult SD rats (n = 48) were categorized into group 1 (sham control), AMI, AMI + ADMSCs (1.2 × 106) cells] and AMI + SVF (1.2 × 106) cells]. Flow cytometric and qPCR analyses showed that the expressions of surface biomarkers for endothelial progenitor cells, and cardiac-stem cells were significantly higher in the SVF population than in the ADMSC population, whereas MSCs showed a reversed pattern between these two groups (all P < 0.001). By day-42 after AMI, LVEF was highest in SC, lowest in AMI, and significantly higher in AMI + SVF than in AMI + ADMSCs (P < 0.0001). Protein expression indicating angiogenesis, anti-inflammatory/anti-apoptotic, mitochondrial/bioenergy-integrity and antifibrotic biomarkers showed an identical pattern, whereas protein expressions for inflammatory, apoptotic and pressure-overload/heart failure biomarkers exhibited an opposite pattern to LVEF among the four groups (all P < 0.001). Histopathology displayed that LV infarction/fibrotic area/collagen-deposition areas, cellular expressions of DNA-damage, and inflammatory biomarkers exhibited an opposite pattern, whereas cellular expressions of endothelial/gap-junction biomarkers showed an identical pattern to LVEF among the four groups (all P < 0.0001). Cellular expression of angiogenesis biomarkers significantly and progressively increased from groups 1 to 4 (all P < 0.0001). In conclusion, SVF may be better than ADMSC at improving LVEF in rat after AMI.
