exVive3D™ Liver, Tissue Performance

Organovo's exVive3D™ Liver, bioprinted human tissue models are created using proprietary 3D bioprinting technology.  The resulting tissues contain precise and reproducible architecture that can remain fully functional and stable for greater than 40 days. exVive3D™ Liver models will be initially be made available through Organovo’s preclinical in vitro  testing to provide predictive liver tissue specific toxicity marker assessment as a supplement to in vitro and preclinical (non-GLP) animal testing.
