中文摘要

Background: We investigated the potential benefits and the underlying mechanisms of autologous bone marrow-derived mononuclear cell (BMDMNC) implantation in a porcine model of acute anterior wall myocardial infarction (AAWMI) by studying 6-month left ventricular (LV) function and LV remodeling.
Methods: After being aspirated from the iliac crest and cultured for 1 week, BMDMNCs were implanted immediately after AAWMI induction through the left anterior descending artery ligation. Thirty male mini-pigs (16-18 kg) were equally divided into group 1 [ AAWMI plus saline injection into infarct-ischemia area (IA)], group 2 (AAWMI plus 3.0x10(7) BMDMNC transplantation into non-IA), group 3 (AAWMI plus 3.0x10(7) BMDMNC transplantation into IA), group 4 (sham control plus 3.0x10(7) BMDMNC transplantation into LV myocardium), and group 5 (normal control).
Results: By day 90, echocardiography demonstrated an increased LV end-diastolic and end-systolic dimensions but reduced LV ejection fraction (LVEF) in groups 1 and 2 than in other groups (all p<0.01). Six-month angiographic study showed a lower LVEF and wall motion score but a higher mitral regurgitation in groups 1 and 2 than in other groups (all p<0.01). In IA and peri-infarct area, the number of small vessels and mRNA expressions of endothelial nitric oxide synthase, Bcl-2, interleukin (IL)-10, and peroxisome proliferator-activated receptor-gamma coactivator-1 alpha were lower, whereas the number of apoptotic nuclei, caspase-3, Bax, endothelin-1, IL-8, and matrix metalloproteinase was higher in groups 1 and 2 than in other groups (all p<0.01).
Conclusions: Autologous BMDMNC transplantation into IA rather non-IA improves LV function and reduces LV remodeling via eliciting a broad-spectrum of molecular-cellular defensive mechanisms. (C) 2010 Elsevier Ireland Ltd. All rights reserved.
