Liver Toxicity Imaging Analysis
The liver is a central metabolic organ and is easily damaged by chemicals and/or their metabolites entering the body. Drugs have a special risk of causing drug-induced liver injury (DILI). Liver toxicity is an important reason for withdrawal of drugs from the market, which brings huge economic losses to pharmaceutical companies. Therefore, it is important to create an in vitro model that can effectively evaluate liver toxicity, and to identify and eliminate potentially problematic compounds in the early stages of drug discovery.

Liver Toxicity Imaging Analysis
The monolayer culture of primary hepatocytes to determine the effect of drugs on cell viability provides an overall measure of liver toxicity, but this method cannot reveal the specific mechanism of drug toxicity due to the lack of 3D tissue and non-parenchymal cells. CD BioSciences can not only use traditional monolayer cell models to evaluate the liver toxicity effects of test compounds, but also use 3D liver tissue models to evaluate the liver toxicity effects of test compounds. The 3D liver tissue model is formed by culturing hepatocytes and non-parenchymal cells at a nearly physiological ratio using the transwell method.

Liver Toxicity Imaging Analysis Workflow
CD BioSciences uses high-content screening to perform imaging analysis of liver toxicity. The detailed steps are as follows:
For 3D cell models, grown to approximately 200 μm in diameter. Adherent monolayers cultured to confluence.
Treatment with test compounds.
Labeling with fluorescent probes.
For 3D cell models, tissue clearing is applied to render 3D cell models transparent.
High content imaging is conducted on well plates.
Images are analyzed to quantify assay endpoints.
