  • In Israel, learned to print live hearts on a 3D printer

    Employees of Tel Aviv University were the first in the world to print on a 3D printer a living pulsating heart of human tissue. This is the most important historical achievement, opening the way to the medicine of the future when for each patient it will be possible to create personalized organs.


    "Scientists from the laboratory of Professor Tal Dvir at the University of Tel Aviv were able to solve one of the main problems of modern medicine: using a 3D printer, they printed a living heart from human tissues taken from the patient. This study opens the way for the medicine of the future when patients no longer have to wait for organs to be transplanted or take medications to prevent their rejection. Instead, the necessary organs will be printed directly in hospitals, fully personalized for each patient," the University said in an official statement.

    The printed heart is about 2.5 centimeters long and is comparable in size to the heart of a rabbit or other small animal. For its printing, the patient's fat cells were used, which were converted into stem cells of the cardiovascular muscle, and then mixed with connective tissue. It took three and a half hours to seal the heart.

    As part of the experiment, the researchers intend to print a few dozen hearts that will be transplanted to animals to check the performance of the organ. Scientists believe that the printing and transplantation of human hearts will be possible in the next ten years.
