Important progress has been made in the research of artificial heart

　　Now, the biological engineer of John Paulson College of Engineering and Applied Sciences (SEAS) of Harvard University in the United States has developed the first biological hybrid model of human ventricle with beating heart cells in spiral arrangement by using a new additive textile manufacturing method (FRJS), and proved that its muscle arrangement can indeed significantly increase the amount of blood pumped by the ventricle at each contraction. The related research results were published in the July 7th issue of Science.
