3D-printed highly uniform embryonic stem cells as building blocks of life


Scientists have developed a 3D-printing method capable of producing highly uniform blocks of embryonic stem cells. These cells – capable of generating all cell types in the body – could be used as the ‘Lego bricks’ to build tissue constructs, larger structures of tissues, and potentially even micro-organs. The results are published today in the journal Biofabrication. “It was really exciting to see that we could grow embryoid body in such a controlled manner,” explains Wei Sun, a lead author on the paper. “The grown embryoid body is uniform and homogenous, and serves as much better starting point for further tissue growth.”
