Astronaut Oleg Kononenkocurrently working on the ISS, will try to print blood vessels and other tubular organs of the human body, RSC Energia reported on Sunday.

The bioprinter is already in orbit. Moreover, they have already tried to grow tissues of cartilage, pancreas and bone on it.

Tubular parts of the human body, such as blood vessels or the urethra, are more difficult to manufacture. Now launched on its second attempt, Soyuz MS-25 is carrying “consumables” to the ISS—plates with a shape memory effect, on which a layer of cells is applied.

Strictly speaking, the device being experimented with on the ISS is not exactly a printer. Organs in it are grown from tissue spheroids – living “bricks”, each of which contains from 1 to 30 thousand cells – under the influence of a magnetic field. The paramagnetic compounds used for this are very toxic, and weightlessness makes it possible to get by with their low concentration.
