Chinese company releases world's first 3D blood vessel bio-printer

A Chinese biotechnological company, Revotek, on Sunday announced it has developed the world's first 3D blood vessel bio-printer

With two nozzles working alternatively, the bioprinter can finish a 10cm blood vessel within two minutes.

The core of the printer is the BioBrick which contain stem cells. And under certain conditions, the  stem cells can be stimulated to differentiate into any required cell.

A major difference between the 3D blood vessel bioprinting and other 3D printings is that it (3D bio -printing) has to keep the stem cells active during the process.

The new breakthrough is outstanding because it will prove useful in printing blood vessels and other organs like livers and kidneys, according to Dai Kerong, an academic at the Chinese Academy of Engineering.

3D blood vessels like every human blood vessel will transport nutrients to organs making them indispensable elements when creating artificial organs.

Dai added that although the breakthrough has a lot of potentials, there can be a long time before it can be applied to human medical care.

What this means is, artificial organs will soon have their own blood supply and body parts could be replaceable in a not so distant future.
