American scientists have developed a method which allows manufacturing using 3D printer living tissues. Implanted by scientists into the bodies of animals bones, muscles and cartilage made on a 3D printer, operate normally, reports the BBC.
According to experts, the integration of human stem cells in made on a 3D printer a copy of the authority may make a revolution in medicine.
According to the new method, the bodies are made of biodegradable plastic, which forms the external structure of the reconstructing body, and the water-based gel that contains the cells and stimulates their growth. Animal testing has shown that after implantation the plastic is gradually destroyed, and its place is taken by a natural structural matrix of proteins produced by cells. Blood vessels and nerves vredeveld directly to the implants.
