‘A team of scientists from Beijing’s Tsinghua University have reportedly devised a means of producing uniform embryonic stem cells with a 3D printer. These cells stack like organic Lego bricks and could form the structural basis for future lab-grown organs. “It was really exciting to see that we could grow embryoid body in such a controlled manner,” lead author Wei Sun said in a statement. “The grown embryoid body is uniform and homogenous, and serves as a much better starting point for further tissue growth.” The study published yesterday in the journal Biofabrication.
These cells are created by extruding biological material from a printer onto a three-dimensional grid structure. This differs from existing methods like growing them in petri dishes (which results in sheets of cells) or the “suspension method” where cells grow like stalagmites in liquid nutrient baths. “However,” Sun continued, “these don’t show the same cell uniformity and homogenous proliferation.” Only the 3D-printed method is able to produce the cellular structures that the researchers were after.

I'm envisioning what one of these pieces would look like on the wall of my office. It would look awesome!...
