Defined as a major medical breakthrough, scientists in Israel revealed a 3D print of a heart with human tissues and vessels. In the past, medical researchers across the globe have managed to 3D print the structure of a heart, but this is the first time that a printed heart has cells or blood vessels. The heart produced by the group of Israeli scientists is mini and of the size of a rabbit’s.
A biopsy of a human fatty tissue was used to develop the ink for the 3D print. According to the research team, it is important to use the patient’s tissue to avoid implant risks and to also prevent transplant rejection.
In the future, the team of scientists will work on the functionality of the printed heart and hope to make it suitable for human transplants. Currently the cells are only able to contract, they cannot pump. The team plans to experiment the transplant into animal models. As a futuristic aim they see organ printers being used on a regular basis in hospitals, although the idea of printers for simpler organs than hearts seem more viable in the present medical scene.
