Scientists at Tel Aviv University unveiled a 3D-printed heart with human tissue and vessels on Monday, calling it a first and a “major medical breakthrough” that advances possibilities for transplants.

The heart marked “the first time anyone anywhere has successfully engineered and printed an entire heart replete with cells, blood vessels, ventricles and chambers,” said Professor Tal Dvir, who led the project.

“People have managed to 3D-print the structure of a heart in the past, but not with cells or with blood vessels,” he said.

But the scientists said that many challenges remain before fully working 3D-printed hearts will be available for transplant into patients.

Journalists were shown a 3D print of a heart about the size of a cherry at Tel Aviv University as the researchers announced their findings, published in the journal Advanced Science.

“Maybe, in 10 years, there will be organ printers in the finest hospitals around the world, and these procedures will be conducted routinely,” he said.

But he said that hospitals would likely start with simpler organs than hearts.
