Scientists create world's first patient-specific vascularized 3D-printed heart

Next, the stem cells were mixed into batches of the gel, after which they were prompted to differentiate into either cardiac or endothelial cells, the latter being cells that line the interior surface of blood vessels. This resulted in two types of “bio-ink” that were then extruded from the nozzle of a 3D bioprinter and into an alginate/xanthan gum supporting medium. Building up biological tissue layer by layer, this approach was first used to make patches of cardiac tissue, after which the complete heart was made.
