Sumario: | OBJECTIVE(S): Background: Impaired coronary blood flow causes cardiac ischemia. Cellular therapy is a new approach to the treatment of myocardial ischemia. This study aimed to investigate the effect of adipose tissue-derived mesenchymal stem cells (AD-MSCs) conditioned with vasopressin on oxidative stress, perivascular collagen, and angiogenesis caused by myocardial infarction (MI) in rats. MATERIALS AND METHODS: We divided 40 male albino Wistar rats into 4 groups; Control group; No intervention; in experimental groups, after it generated induced MI on models, it divided into three groups: Vehicle group (150 μl of cell-free culture medium received); ASC-MI group (6× 10(6) AD-MSC received) and AVP-ASC-MI group (received 6 × 10(6) AD-MSC conditioned with 10 nM vasopressin). Then, histologic parameters and anti-oxidant enzymes were evaluated 7 days post-MI cell injection. RESULTS: Arterial muscle diameter improved and collagen deposition around the coronary arteries decreased in cell-received groups compared with the vehicle group. Malondialdehyde (MDA), catalase (CAT), (GSH) Glutathione, and Total Anti-oxidant Capacity (TAC) parameters were not significantly different between the cells received groups compared with the vehicle group. But the Catalase (CAT) parameter in the ASC-MI group had a significant increase from the control group. CONCLUSION: We prepared direct evidence that intramyocardial injection of AD-MSCs reveals the positive cardiac remodeling post-MI in rats, and these useful effects can be more enhanced by administrating injection of conditioned ADSCs with vasopressin. |
