The objective of this study was to engineer a three-dimensional (3-D) liver model using chitosan-based nanofiber scaffolds and co-culture system (adult rat hepatocytes and 3T3-J2 fibroblasts) to mimic the natural liver and to justify its application for in vitro drug screening. Chitosan nanofiber scaffolds were fabricated by electrospinning technique. In order to promote cell adhesion on the chitosan scaffolds, the scaffolds were coated with a cell adhesion molecule, fibronectin, by adsorption. The effects of mono-culture and co-culture systems on the proliferation and functional activities of hepatocytes were investigated. Lastly, the utilization of the optimized 3-D model for drug screening was tested. The results showed that 3-D in vitro liver model in co-culture maintained hepatic morphology and shows suitable liver function such as albumin secretion for a prolonged period.
