Functional three-dimensional human liver tissue created with 3D bio-printer

Back in 2009, we heard about a 3D bio-printer that had been developed through a collaboration between Australian engineering firm Invetech, and Organovo, a San Diego-based regenerative medicine company. The device incorporates two print heads – one for placing human cells, and the other for placing a hydrogel, scaffold, or support matrix. At the time, the hope was that the printer could someday be used to create organs for transplant purposes. Recently Beth Coxworth from gizmag reported that Organovo announced that it has succeeded in using the device to create three-dimensional functioning human livers – albeit tiny ones.
