Organovo用3D打印出功能正常的肝脏组织

At Organovo, we design and create functional human tissues using our proprietary three-dimensional bioprinting technology. Our goal is to build living human tissues that are proven to function like native tissues. With reproducible 3D tissues that accurately represent human biology, we are enabling ground-breaking therapies by:
Partnering with biopharmaceutical companies and academic medical centers to design, build, and validate more predictive in vitro tissues for disease modeling and toxicology.
Giving researchers something they have never had before: the opportunity to test drugs on functional human tissues before ever administering the drug to a living person; bridging the gulf between preclinical testing and clinical trials.
Creating functional, three dimensional tissues that can be implanted or delivered into the human body to repair or replace damaged or diseased tissues.
