Cardiac Regeneration using 3-Dimensional Cardiac Tissue

点击翻译按钮获取中文摘要

We fabricated scaffold-free 3-Dimensional functional cardiac tissue using spheroid based technology. Proper cardiac tissue spheroids are fabricated with cardiomyocytes, dermal fibroblasts, and vascular endothelial cells. We also fabricated 3-D cardiac tissue with the diameter 1cm, and these constructs were implanted to nude rat heart. Furthermore, implantation for acute myocardial infarction nude rat model indicates improvement of left ventricular ejection fraction.
