Research three-dimensional biological printers producing kidneys

Russia's first 3D bio-printer makers promise in 2015 to print off the functioning organs. That will be thyroid. They believe in the prospect of their 3D biological printer products.

Every year in the world, up to 25% of patients die because of inadequate organ transplantation. The regenerative medicine industry is growing rapidly as a new alternative to donated organs. A research direction here is 3D biological printer.

The idea of ​​the technology of printing organs on a special device belonged to Russian scientist Vladimir Mironov and he raised it in 2003. Since then, the world has formed a specialized research community. focus on this topic. Science has made certain progress: for example, the technology of making three-dimensional models of internal organs from natural or artificial materials, then using 3D biological printers to insert cells into the model . This frame will be regenerated into connective tissue. But Mr. Vladimir Mironov proposed a more unique method of printing birth c without any other than living cells. Equipment is being tested in the laboratory of the scientist.

Performing the "ink" function here are living cells, more precisely, spheroid cells . They are also manufactured using special equipment. When linked together, the cells form three-dimensional solid tissue. "Paper" in Russia's 3D biological printer is hydrogel . The printer extracts hydrogel and installs on the 'paper' multi-cell sphere. The work takes place according to the model established by the computer. Then, the printed part will be 'mature' in a bioreactor.

However, the most complicated task is to provide blood vessels for the created parts. The Russians were able to print different size circuits and very thin buttercups. The next task is to take the method of attaching the internal organs to the vascular system.

Vladimir Mironov said that bio-printing technology will allow solving all problems of transplanting parts of the body. There is no longer a need to donate organs, the printed parts are adaptable because they are made from the patient's own cells.

Russia's 3D biological printing device was born in just six months. Scientist Vladimir Mironov said, this printer is the best in the world today thanks to its flexible functions. It can work with spheroid types, link them in different combinations and use a variety of hydrogels.

On March 15, 2015, Mr. Vladimir Mironov and his colleagues plan to successfully print a thyroid gland that functions properly. However, it will be the mouse's thyroid, not human. By 2018, scientists plan to capture kidney manufacturing technology.
