A three-dimensionally-printed heart made from human tissue, with blood vessels, ventricles, and chambers.

A team of scientists at Harvard University recently developed a technique through which they created perfusable cardiac tissue.

This year has witnessed advances in three-dimensional (3D) printing of organic tissue, including an announcement from scientists in Israel of the creation of perfusable cardiac tissue that was able to beat.

This achievement involved reprogramming fatty-tissue cells into pluripotent stem cells cultured into cardiac muscle via growth-factor molecules.

Meanwhile, researchers at the U.K.'s University of Edinburgh have been designing bioprinted implantable tissue to treat diseased livers by converting stem cells into spherical material that can survive in culture for more than a year; the ultimate goal is an implantable graft.

Edinburgh's David Hay expects 3D-printed skin to become the first clinically established bioprinting application.
