Presented in the heart of the world's first printed the 3D-printer of human tissues
Scientists from around the world are trying to use 3D-printing technology to create artificial organs. If they can prove their safety, effectiveness and durability in the future, humanity will be able to forget about the donation, and to introduce into the body of people of their artificial counterparts need healthy bodies. Previously, researchers from Switzerland managed to create a mechanical copy of the human heart, but it was printed in silicone. Since silicone can be rejected by the body, scientists should create the heart of the natural human tissue - is it finally succeeded.
So, at least, say scientists from Tel Aviv University - for printing small heart they are just using human tissue, which will not be rejected by the body. The structure includes an artificial organ needed for its deliberations vessels, collagen protein to build connective tissue and a variety of biological molecules.
This is the first time that someone has successfully designed and printed the whole heart of the cells, blood vessels, the ventricles and cameras.

In the "personalized hydrogel" was used as a biological ink for the printing of the heart, which is based on fatty tissue extracted from a human body. The researchers claim that the heart is able to be reduced, but it is important to achieve that its cells have begun to work together. Talk about what the heart is able to fully replace organ donor, it is too early - researchers have to work on all the negatives found.
How do you think, will the authorities printed the 3D-printer to save humanity from the need to transplant donor hearts, kidneys and other body parts? Share your opinion in the comments or in our Telegram-chat.
