Human hepatic organoid model to test for drug-induced liver fibrosis
Scope of the method
- Human health
- Basic Research
- Translational - Applied Research
- In vitro - Ex vivo
- Human derived cells / tissues / organs
- Hepatic organoid
- drug-induced liver injury
- Hepatic stellate cell
- HSC co-culture
- Liver fibrosis
- liver disease
- Toxicity testing
This model is a 3D human co-culture model where both hepatocyte functionality and HSC quiescence can be maintained for at least 21 days. This novel system allows hepatotoxicity testing and can detect drug-induced as well as hepatocyte-dependent HSC activation, thereby representing an important step forward towards in vitro compound testing for drug-induced liver fibrosis.
- - Incubator,
- - Orbital shaker,
- - Confocal fluorescent microscope.
Pros, cons & Future potential
- - The spheroid formation procedure is highly reproducible.
- - The model can be used for single or repeated dose exposure.
- - The hepatic organoids are sensitive to the nature of the compounds.
- - The model can be used to identify compounds that induce fibrosis, a drug-induced liver injury (DILI) rarely addressed in vitro.
- - The model represents a substantial improvement in terms of cost, animal use and prediction of liver fibrosis in human.
- - The culture depends on primary human HSCs, although also hiPSC-HSCs can be used.
- - Only one cellular source of hepatocyte-like cell is used.
- - One needs to test the cell repellent plates before use since HSCs do attach to many cell-repellent or low cell attachment plates
Similar ratios can be used for primary liver cells as well (for mouse Hepatocyte/HSC cultures see Mannaerts, I., Eysackers, N., Anne van Os, E., Verhulst, S., Roosens, T., Smout, A., Hierlemann, A., Frey, O., Leite, S.B., and van Grunsven, L.A. (2020). The fibrotic response of primary liver spheroids recapitulates in vivo hepatic stellate cell activation. Biomaterials 261, 120335.)
- - The model could be used to further optimize the AOP of liver fibrosis.
- - The model could stimulate the development of culture models representative of fibrosis in other organs such as lung and kidney, since these share common mechanisms.
