Israel Has Completed the First 3D Printed Human Heart with Blood Vessels and Cells
Recently, Israeli researchers announced major breakthroughs in organ transplantation: They used 3D technology to print the world's first complete heart, including cells and blood vessels from human cells and tissues. The size of the heart is similar to that of a rabbit heart. The next step is to cultivate its blood pumping function and complete animal transplantation.
"This is the first time someone has successfully designed and printed a whole heart filled with cells, blood vessels and chambers," said Tal Devil, associate professor of molecular microbiology and biotechnology at Tel Aviv University. In the past, people have successfully printed out the structure of the heart using 3D printing technology, but patients who do not use cells or blood vessels will no longer need to wait or take drugs to prevent rejection. Instead, the technology prints out the organs needed by patients and can be tailored to each patient. "This heart is made of human cells and patient-specific biomaterials. In the course of our research, these materials can be used for 3D printing of complex tissue models as biomass inks composed of sugar and protein, "Professor Deville said.
