Scientists use 3D-printed building blocks to produce life

Researchers from the Tsinghau University in Beijing, China and Drexel University in Philadelphia, USA, have developed a new extrusion-based 3D-printing method. The method produces uniform blocks of embryonic stem cells, capable of generating all cell types in the body. The results, published in the Biofabrication journal, show the blocks could be used to build tissues constructs, potentially even micro-organs. It is the first method of printing that shows a higher level of uniformity.
