Scientists have developed a 3-D 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.
