BACKGROUND Human mesenchymal stromal cells (MSCs) have been reported to preserve cardiac function in myocardial infarction (MI) models. Previously, we found a beneficial effect of intramyocardial injection of unstimulated human MSCs (uMSCs) on cardiac function after permanent coronary artery ligation. In the present study we aimed to extend this research by investigating the effect of intramyoc...
Intramyocardial Injection of Stem Cells in Pig Myocardial Infarction Model: The First Trial in Korea
Although cell therapy is emerged for cardiac repair, its efficacy is modest by intracoronary infusion. Therefore, we established the intramyocardial delivery technique using a left ventricular (LV) mapping system (NOGA® XP) using 18 pigs. After adipose tissue-derived mesenchymal stem cells (ATSCs) were delivered intramyocardially to porcine infarcted heart, LV ejection fraction (EF) was increas...
In experimental studies, mesenchymal stem cell (MSC) transplantation in acute myocardial infarction (AMI) models has been associated with enhanced neovascularization and myogenesis. Clinical data however, are scarce. Therefore, the present study evaluates the safety and feasibility of intramyocardial MSC injection in nine patients, shortly after AMI during short-term and 5-year follow-up. Perip...
Intramyocardial injection of bone marrow mononuclear cells (MNCs) with hyaluronan (HA) hydrogel is beneficial to the ischemic heart in a rat model of myocardial infarction (MI). However, the therapeutic efficacy and safety must be addressed in large animals before moving onto a clinical trial. Therefore, the effect of combined treatment on MI was investigated in pigs. Coronary artery ligation w...
RATIONALE Transcatheter, intramyocardial injections of bone marrow-derived cell therapy produces reverse remodeling in large animal models of ischemic cardiomyopathy. OBJECTIVE We used cardiac MRI (CMR) in patients with left ventricular (LV) dysfunction related to remote myocardial infarction (MI) to test the hypothesis that bone marrow progenitor cell injection causes functional recovery of ...
After initial reports of successful stem cell delivery to the injured heart, the clinical feasibility and safety of this new therapeutic strategy has been established, thereby focusing on the treatment of ischemic heart disease. Over 3000 patients with either recent myocardial infarction or chronic ischemic heart failure have been treated so far by means of interventional cardiology and cardiac...
BACKGROUND AIMS Mesenchymal stromal cells (MSC) may improve cardiac function following myocardial infarction. MSC can differentiate into cardiomyocytes and endothelial cells while exerting additional paracrine effects. There is limited information regarding the efficacy of route for MSC treatment of severe dilated cardiomyopathy (DCM). The aim of this study was to demonstrate the clinical safet...
