Bone marrow mononuclear cells(BMMNCs) have become one of the candidate seed cells in treatment of myocardial infarction because of its advantages of easy separation and no immune rejection. The previous experiments in vivo have proved the improved cardiac blood circulation and systolic function in animal models after BMMNCs transplantation by producing the secretions of growth factors and other proteins to promote angiogene...
