Japanese scientist Makoto Nakamura is on a mission to see if the technology of a simple inkjet printer found in homes and offices, can also produce human organs. The idea is for the printer to jet out thousands of cells per second -- rather than ink droplets -- and to build them up into a three-dimensional organ. Much like a printer chooses different colors, the machine can position different types of cells to drop. Nakamura has succeeded in building a tube with living cells with a 3D inkjet bioprinter. It measures one millimeter in diameter and has double walls with two different kinds of cells, similar to the three-layer structure in human blood vessels.
There are really all kind of things, but instead of shaking our heads I propose to rejoice because we might soon be enabled to create artifical organs what would bring us yet another step further to immortality. And some of the current problems with organ trade could diminish. We would not need feed on the organs of poor donors anymore nor would they only receive scrapped organs themselves.
