Print the first heart using a 3D printer


A heart that beats

The group of researchers who have achieved this feat belongs to the University of Tel Aviv. The director of the research group, Tal Dvir, said in a statement that «this heart is made of human cells and biological materials specific to the patient. We take a small biopsy of the patient’s fatty tissue, remove all the cells and separate them from collagen and other biomaterials, reprogram them into stem cells and then differentiate them into heart cells and blood vessel cells. The biomaterials are then processed into «biotint,» which will allow printing with the cells. Previously, it had been possible to print the structure of a heart in 3D, but not with cells or blood vessels. Our results demonstrate the potential of this technique for tissue and organ customization in the future.
