3D printers are rapidly changing the life of a modern person. On such devices today you can already print not only buttons and chess pieces, but also confectionery, firearms and whole houses. However, this is far from the limit. capabilities of such printers.
World scientists are convinced that in the near future technology printouts of bulk matter will allow you to get full human organs for transplantation. And this future is much closer than many of us can imagine. People of science already achieved the first significant success in this area.
The last few decades, experts are concerned about acute lack of donor tissue. Most recently in the united states was 3D printer designed to recreate muscle structures and human tissue. American scientists using technology volume printing, as an experiment created from biomaterials artificial ear and implanted it under the skin of a laboratory mouse. TO to the great amazement of researchers, the organ has taken root and has grown circulatory system.

The organs printed on the 3D printer perfectly got accustomed
The authors of the know-how were the employees of the medical center Wake Forest University of North Carolina. Lately these experts carefully studied the bioprinting method in order to learn replace damaged tissues of the human body with formed ones 3D printer surrogates. As a result, the Americans developed unique printing device and true biological ink. Ink is a special water-based biogel. is he contains lattice biodegradable polymer, stem cells and tissue growth promoting substances.
Microchannels were formed in the ear for entry from the body mouse oxygen and nutrients. The size of the organ was fifteen by thirty eight millimeters. Scientists have implanted an ear under the skin of the mouse and began to wait, daily studying the condition of the implant. A month later, signs of vascularization were detected in the tissues of the ear. Amazingly, in an artificially created organ formed full blood vessels.
The Americans have already managed to grow a piece of muscle in this way, fragment of the jaw and nose. Researchers do not hide their optimism: “Our biological ink printer is a huge step humanity to meet the massive creation of stem cells full organs for transplantation. ”
