Researchers Develop First Printed 3D Heart

Researchers at Tel Aviv University (TAU) in Israel have created a three-dimensional (3D) fully vascularized human heart from human cells obtained through biopsies. The 3D heart matches the immunological, cellular, biochemical, and anatomical properties of the patient. The biopsy samples were experimentally reprogrammed to become “pluripotent,” or de-identified stem cells, and then exposed to chemicals or “bioinks” that retrained them to reconstitute themselves as either heart or blood vessel cells. The engineered heart is about the size of a rabbit’s heart. Though it is still in the early stages of development, the invention represents a breakthrough for transplant medicine. Said the university’s Tal Dvir, “Our results demonstrate the potential of our approach for engineering personalized tissue and organ replacement in the future.”
