3D printing of kidney tissue, the first to achieve the same as the true kidney – Sohu Technology ca1806

3D printing kidney tissue, for the first time to achieve the same as the real kidney work – Sohu scientists with 3D printing to create a small precision tube, it can work as the core components of the kidney. Although in real manufacturing can replace the "artificial kidney kidney", have more work to do, but this result is very important, because the 3D print out kidney first can play a role like kidney. The inventors say the current artificial tissue could be used in vitro to assist people who lose their kidney function, or to test the toxicity of new drugs. For more than 20 years, researchers have been trying to make artificial kidneys, but because of the three-dimensional structure of the kidney and the fiber structure is essential to its function, the reconstruction of the kidney becomes complex and challenging. However, the demand for artificial kidney is very urgent. About 10% of the world’s population is suffering from chronic kidney disease. In order to survive, millions of people rely on dialysis, and dialysis treatment itself is very time-consuming – God in the whole process, the blood will be drawn through the filter and then return to the body. But in the end dialysis machine than the kidneys, so in the United States each year about 16000 people to receive a kidney transplant, and another 100 thousand people waiting for donations. The use of "3D bio printer", researchers can print out the structure of 3D is an important part of the kidney kidney is Harvard India played Jennifer · Lewis (Jennifer Lewis) in the latest achievements of Harvard University laboratory. The technique is able to print complex structures in different human tissues while maintaining the vascular system necessary for the survival of this tissue. This printing method uses a variety of similar gel ink". After the printing is completed, the researchers will remove one of the ink, leaving a hollow tube. Then they join the cells to grow and eventually become an organization. Laboratory tests show that this artificial tissue has a true renal function, which was previously achieved from the. In particular, they are the basic functional unit of the kidney, the proximal renal tubule. The kidneys filter the blood, retain what is useful to the body and remove the remaining. If scientists can make kidney cells, in theory, they can also make the kidneys, but it needs to develop several additional interconnections, which may take years.
