  Scientists in Israel unveiled a 3D print of a heart with human tissue and vessels1 on Monday.   以色列科学家周一展示了一个用人体组织和血管3D打印的心脏。
    While it remains2 a far way off, scientists hope one day to be able to produce hearts suitable for transplant into humans as well as patches to regenerate3 defective4 hearts.   The heart produced by researchers at Tel Aviv University is about the size of a rabbit's.   It marked "the first time anyone anywhere has successfully engineered and printed an entire heart replete6 with cells, blood vessels, ventricles and chambers," said Tal Dvir, who led the project.   "People have managed to 3D-print the structure of a heart in the past, but not with cells or with blood vessels," he said.   But the scientists said many challenges remain before fully5 working 3D printed hearts will be available for transplant into patients.
