Abstract
With the advent of induced pluripotent stem cells and directed differentiation techniques, it is now feasible to derive individual-specific cardiac cells for human heart tissue engineering. Here we report the generation of functional engineered human cardiac patches using human induced pluripotent stem cells-derived cardiac cells and decellularized natural heart ECM as scaffolds. The engineered human cardiac patches can be tailored to any desired size and shape and exhibited normal contractile and electrical physiology invitro. Further, when patching on the infarct area, these patches improved heart function of rats with acute myocardial infarction invivo. These engineered human cardiac patches can be of great value for normal and disease-specific heart tissue engineering, drug screening, and meet the demands for individual-specific heart tissues for personalized regenerative therapy of myocardial damages in the future.
