Abstract/OtherAbstract:
To improve cellular cardiomyoplasty efficacy after myocardial infarction (MI), we postulated that combining mesenchymal stem cells (MSCs) transplantation with anti-apoptotic and angiogenic effects of erythropoietin (EPO) and vascular endothelial growth factor (VEGF) may provide better prognosis in an infarcted heart 48 rats, underwent left anterior descending artery ligation, were divided into eight groups and treated as follows: Group 1: MSC+EPO+VEGF, Group 2: MSC+EPO, Group 3: MSC+VEGF, Group 4: MSC, Group 5: EPO+VEGF, Group 6: EPO, Group 7: VEGF and Group 8: Control. After MI induction, EPO and VEGF were injected subcutaneously at the dose of 3000U/kg and 3µg/kg respectively. MSCs were transplanted one week after MI. In the fourteenth and sixteenth days after infarction, EPO was injected again. Echocardiography demonstrated that all treatments improved left ventricular function significantly (before vs. after treatment) but in control group ejection fraction deteriorated over the 2-months period. Percent of ejection fraction recovery in all treatment groups were significantly greater than control (P<0.05). Compared with the control group, all treatments attenuated cell death in peri-infarct areas significantly, except groups 6 and 7. Vascular density of all treatment groups were more than control group but this superiority was statistically significant only in group1 (P<0.01). All of our treatments had beneficial effects to some extent but MSC transplantation combined with EPO and VEGF administration resulted in superior therapeutic outcome in enhancing cell survival and neovascularization.
