First fully-cellular liver tissue 3D bioprinted at Organovo

Bioprinted human liver with CD31+ microvessels (green) forming within the tissue.

Since liver cells are used in labs to test the toxicity and efficacy of drugs, these printed tissues will first serve that purpose. Soon though, a larger liver will be printed, and it won’t be long after that that printed organs will be tested in animals. It’s a short hop from there to humans.
