Professor Angela Panoskaltsis-Mortari from the University of Minnesota has made a remarkable discovery in the field of transplantation - three-dimensional Biobots bioprinters can print oesophageal tissues beyond human body cells. The device uses a special aqueous gel created from cells and natural materials, passing it through a three-dimensional nozzle. The first, experimental transplantation will probably be performed on a pig before the end of this year.

If the experiment is successful, patients will not have to suffer for a long time waiting for donor organs, which are not always accepted. The inventor claims that the artificial oesophagus could be accepted by the human body much more often.

There are currently 20 Biobots printers in the world.
