In a groundbreaking new study, researchers at the University of Minnesota have 3D printed a functioning centimeter-scale human heart pump in the lab. Videos show the production of the human heart using a 3D bioprinter and its function in pumping fluids. The discovery could have major implications for studying heart disease, one of the leading causes of death in the world.
