Researchers at the University of Tel Aviv in Israel have created a three-dimensional, fully vascularized human heart using a 3D printer.
Modeled on a human patient, the 3D heart “[matches] the immunological, cellular, biochemical, and anatomical properties of the patient,” Dr. Tal Dvir, study researcher and professor of molecular cell biology at Tel Aviv University, said in a press release announcing the event. The heart is made from human cells, and “patient-specific biological materials.” It was created from human cells obtained through biopsies.This achievement, first time in the history, represents a breakthrough for transplant medicine, as it may impact the lives of thousands of patients who await heart transplants for end-stage heart failure each year.
For the instant, in the early stage of the experiment, the heart has small dimensions, like a rabit heart. Heart transplantation is oftentimes the only way to improve the quality of life and extend survival of patients suffering from CHF each year. “The biocompatibility of engineered materials [was] crucial to eliminate the risks of implant rejection, which jeopardizes the success of such treatments,” said Dr. Dvir describing the experiment. Further research is needed including the comportment of the organ „in vivo”and that means time but the first result is promising.
