Scientists in Israel unveiled a 3D print of a heart with human tissue and vessels on Monday [April 15, 2019], calling it a first and a “major medical breakthrough” that advances possibilities for transplants.
While it remains a far way off, scientists hope one day to be able to produce hearts suitable for transplant into humans as well as patches to regenerate defective hearts.
The heart produced by researchers at Tel Aviv University is about the size of a rabbit’s.
It marked “the first time anyone anywhere has successfully engineered and printed an entire heart replete with cells, blood vessels, ventricles and chambers,” said Tal Dvir, who led the project.
But the scientists said many challenges remain before fully working 3D printed hearts would be available for transplant into patients.
Researchers must now teach the printed hearts “to behave” like real ones. The cells are currently able to contract, but do not yet have the ability to pump.
Then they plan to transplant them into animal models, hopefully in about a year, said Dvir.
“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.
