Tel Aviv University prints first personalized 3D heart using patient’s own cells


Researchers at Tel Aviv University have successfully printed a partially working, vascularized 3d printed heart, starting from cells obtained from a biopsy of fatty tissues.

The materials from the biopsy were separated and processed into pluripotent stem cells and an extracellular matrix containing collagens, glycoproteins, and other materials which the human heart consists of. A set of hydrogel-based inks was produced and then used to 3d print the heart.

This process is still in the early stages; the heart can contract but not pump. The resulting heart was also the size of a rabbit’s. The printing technology itself still needs improvement. However, the team plans to print working animal hears and begin working on animal testing to further develop the technique.

The process has the potential to create patient-specific hearts from the patient’s own cells – or produce small sections of heart tissue for the repair of an existing heart defect.
