Summary
This review establishes benchmarks for liver-on-a-chip (LoC) development, standardizing cell sources, extracellular matrices (ECMs), and assays. These guidelines enhance reproducibility in hepatic models for drug discovery.
Area of Science:
- Biotechnology
- Hepatology
- Drug Discovery
Background:
- Liver-on-a-chip (LoC) platforms show promise for studying liver function and drug responses.
- Current LoC models exhibit variability in components and assays, hindering reproducibility.
Purpose of the Study:
- To review 2D and 3D LoC systems and identify common practices.
- To establish practical benchmarks for LoC development to improve standardization.
Main Methods:
- Systematic review of reported 2D and 3D LoC studies.
- Analysis of cell types, seeding densities, extracellular matrices (ECMs), and functional assays.
Main Results:
- Immortalized HepG2 cells are dominant; optimal seeding densities range from 3 × 10^6 cells/mL (2D) to 0.5-5 × 10^6 cells/mL (3D).
- Collagen I, often with Matrigel, is the most common ECM.
- Albumin and urea assays (e.g., Abcam ELISA, QuantiChrom DIUR) are robust functional markers.
Conclusions:
- Standardized cell selection, seeding parameters, ECM choice, and assay selection are crucial for reproducible LoC development.
- This work provides essential benchmarks to advance LoC technology for pharmaceutical research.
