The first 3D-printed human stem cells

The shortage of transplantable organs has spawned a fascinating science and market. A liver, for example, is often split among two recipients, while for a cystic fibrosis patient in need of two lungs, it is technically preferable to just swap out both the heart and lungs as a combo unit. The extra heart can then be domino donated to a third party. Bioprinting complete organs en masse is a tough proposition because the identity expressed by each component cell must be individually programmed. Then the cells need to be knitted together in a developmentally sound fashion. Researchers in Scotland, land of Dolly, the first cloned mammal, have recently demonstrated the ability to print human embryonic stem cells. Stem cells, of course, are known for a unique feature — they can program themselves.
