Israeli Scientists Have Printed a 3D Heart

“The future is here, and it’s alive and beating. Scientists at Tel Aviv University have printed the world’s first 3-D heart complete with blood vessels using personalized “ink” made of collagen, a protein that supports the cell structures, and other biological molecules.

The extraordinary breakthrough was reported Monday by lead scientists Prof. Tal Dvir, Dr. Assaf Shapira of TAU’s Faculty of Life Sciences and Nadav Noor, his doctoral student, in Advanced Science.

True, the heart is the size of a rabbit’s, and it doesn’t actually work yet. Dvir pointed out however that “printing” a human-size heart involves basically the same technology.

“We need to develop the printed heart further,” he said. “The cells need to form a pumping ability; they can currently contract, but we need them to work together. Our hope is that we will succeed and prove our method’s efficacy and usefulness.””
