Abstract/OtherAbstract:
OBJECTIVES: To investigate the protective effect of tumor necrosis factor receptor (TNFR) gene modified mesenchymal stem cells (MSCs) transplantation against inflammation and cardiac dysfunction following acute myocardial infarction (AMI). DESIGN: MSCs were extracted from the tibias and femurs of rats and transfected with recombinant adeno-associated viral (rAAV) expressing EGFP (enhanced green fluorescent protein) or p75 (human 75 kilodalton) TNFR at multiplicity of infection of 10(5) particles/cell. Rats with AMI induced by occlusion of the left coronary artery were randomized to MSCs-TNFR transplantation group, MSCs-EGFP transplantation group and MI control group. RESULTS: The effects of MSCs-TNFR transplantation on cardiac inflammation and left ventricular dysfunction were observed after 2 weeks of MI. We found that: 1) MSCs-TNFR transplantation attenuated protein production and gene expression of inflammatory cytokines TNF-, IL-1beta and IL-6; 2) MSCs-TNFR transplantation inhibited cardiomyocytes apoptosis and 3) MSCs-TNFR transplantation improved left ventricular function. CONCLUSIONS: The experimental data show that transplantation with rAAV-TNFR transfected MSCs improves left ventricular function following MI through anti-apoptotic and anti-inflammatory mechanisms.
