With the help of a 3D printer, mini human organs can come in all shapes and sizes. In this video, a cluster of tiny hearts – shown on the right – beat in sync, and another pulsing heart is fused with a spherical, darker-coloured liver. Developed by Anthony Atala and his team at the Wake Forest Institute for Regenerative Medicine in Winston-Salem, North Carolina, the mini-organs represent the first step in developing an entire human body on a chip. The hearts were created by reprogramming human skin cells into heart cells, which were then clumped together in a cell culture. A 3D printer was then used to give them the desired shape and size – in this case, a diameter of 0.25 millimetres.
