The question behind this study
A bioprinted, in vitro liver model combines liver cells with perfusable channels lined by endothelial cells. It examines how this vascular barrier affects molecular transport and cell survival during drug-toxicity testing.
What the study shows
The model combines HepG2/C3A liver cells in GelMA hydrogel with sacrificially printed channels lined by HUVEC endothelial cells.
Compared with channels without an endothelial lining, the lined model slowed molecular passage and improved liver-cell viability.
Open questions
A further question is whether this protective effect improves the accuracy of liver-toxicity predictions.
Conditions for comparison
Compare models using matched drugs, exposure times, endothelial lining and cell sources, with permeability and cell viability assessed separately.
