Israeli scientists reveal world’s first 3D printed heart with human tissue
Scientists in Israel unveiled a 3D print of a heart with human tissue and vessels, calling it a first and a “major medical breakthrough” that advances possibilities for transplants. While it remains a long 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.
Znanstvenici u Izraelu su otkrili "3D" printanje srca s ljudskim tkivom i krvnim žilama- nazvavši to prvim i glavnim medicinskim otkrićem koje unapređuje mogućnosti za transplantaciju.
Iako još postoji dugi put do toga, znanstvenici se nadaju da će jednog dana moći napraviti srce koje će se moći transplantirati u ljude, kao i "dijelove" koji će regenerirati oštećenja na srcu. "Srce" koje je stvoreno na Univerzitetu u Tel Avivu ima veličinu zečjeg srca.
Tal Vir, voditelj projekta, je rekao da je to je prvi puta da je itko i igdje uspješno konstruirao i printao cijelo srce sa stanicama, krvnim žilama, ventrikulima i srčanim komorama.

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