| dc.description.abstract | Liver fibrosis, a characteristic of most liver diseases, results from chronic liver injury in conjunction with the accumulation of extracellular matrix (ECM) proteins1,2. The cellular mechanisms underlying hepatic dysfunction in liver fibrosis in response to mechanical cues (e.g., ECM stiffness and dynamic flow) remain elusive. In this study, we fabricated three-dimensional (3D) perfusable liver models with ECM stiffness values mimicking those in the healthy vs. fibrotic states of the human liver. Engineered liver models retained viability, proliferation, and function of both human endothelial and hepatic cells during a 2-week culture period. Further, the effects of hepatocyte-endothelial cell coculture and dynamic flow conditions (static vs. rocking) were studied in our 3D bioprinted model of liver fibrosis. Finally, a pilot perfusion study was successfully conducted using a customized bioreactor system, demonstrating the robust potential of this 3D bioprinted liver platform to be utilized for intensive in vitro studies of liver diseases. | |
