Background to the research:
There is an urgent need for reliable and reproducible methods to understand liver diseases as current available models do not mimic the pathogenesis of human liver injury and disease progression. Bioengineered liver tissues could represent a robust and biologically relevant hepatic model, where disease mechanisms and drug testing studies can be investigated.
We work on the generation of a novel bioengineered liver preparation with structural integrity that exhibits metabolic and immunological functionality as a dynamic immunocompetent 3D system for disease modelling and liver regeneration.
The tissue engineering approach to fabricate the bioengineered liver tissue combines i) a natural-derived scaffold, obtained through decellularization; ii) a mix of human primary hepatic cells and iii) a customised bioreactor for the support of cell survival. The 3D system will also include the innate intrahepatic immune system, using perfusion of immune cells through the vasculature of the bioengineered preparation.
The 3D innovative preparation will reflect specificity of a native tissue, in use in disease modelling, drug screening or regenerative medicine.
