Building on top of existing 3D printing technology, San Diego-based biomedical group Organovo is developing machines capable of reproducing human tissue. This innovation stems from advances over the last five years that have make it possible to engineer layers of tissue into structures that mimic living organs, with current research drawing primarily from hamster ovary cells. Organovo envisions the technology developing to the point where vital organs are more accessible without reliance on human donors.
