Already something similar had been achieved with the creation of a liver – tiny dimensions, that yes – a few months ago, and now a group of scientists has achieved create a kidney, also small, using 3D printing technology.
The Huazhong University of science and technology researchers have developed a process in which 90% of the cells that are “printed” are alive, What offers remarkable possibilities for the future of the application of this system to medicine and kidney transplants.
In fact, and as explained by Xu Mingen, the researcher this Group Chief, technical is not exactly of traditional 3D printing:
To print one cup [in a traditional 3D printer], we have to fill the object with our material. But this method doesn’t work in cells because the cells contain contain blood vessels and there are spaces between the tissues. We had to make sure that there was enough space between them to grow.
To achieve this, large crops are made to obtain samples of human kidney cells and then These are mixed with a hydrogel, a material rich in nutrients which becomes the material base for the 3D printer.
These mini-rinones work accurately to the human kidneys, and allow filter toxins, metabolizing them and perform secretion of fluids. This new discovery probably take time to be implemented in a practical way, but involves a incredibly promising advance in the segment of organ transplants.
