Hepatotoxicity
XenoTech hepatotoxicity studies assess the risk that a test article may cause toxicity in human, non-human or immortalized human hepatocytes. Critical factors that we consider when performing such studies include:
- Confluent, morphologically normal cells that have been allowed to establish cell-to-cell contact
- Examining potential toxicity by parent compound(s)
- Experimental conditions that allow for metabolism-dependent toxicity to be observed
- Analyzing preparations from multiple humans due to high inter-individual variability (when using human hepatocytes).
It is important to measure endpoints that are well-characterized and understood, carefully choose concentrations of test articles, and treat cells with different concentrations in order to generate concentration-response profiles for early-stage compounds.
