3D-Printed Organs May Soon Be a Reality

View as: Print Mobile App Share:
Multilayered skin, bones, muscle structures, blood vessels, retinal tissue and even mini-organs all have been 3D printed. None are approved for human use.

Wake Forest University scientists are 3D-printing tissues and mini-organs that mimic some of the functional properties of natural human tissues.

Progress is being made in the development of three-dimensionally (3D)-bioprinted organs, with Tal Dvir at Israel's Tel Aviv University anticipating transplantation-viable organs to become available in a decade.

Milestones to date have included Poland-based researchers’ bioprinting of a functional prototype of a pancreas that realized stable blood flow in pigs, and U.S.-based United Therapeutics’ 3D-printing of a human lung scaffold.

Stanford University's Mark Skylar Scott said, "The ability to place different cell types in precise locations to build up a complex tissue, and the capability of integrating blood vessels that can deliver the necessary oxygen and nutrients to keep cells alive, are two [3D] techniques that are revolutionizing tissue engineering."
