Abstract

Insights

A new human liver organoid model accurately predicts drug-induced liver injury (DILI) and individual susceptibility. This organoid-based toxicity screen (LoT) aids drug development and precision medicine.

Area of Science:

  • Drug discovery and development
  • Toxicology
  • Regenerative medicine

Background:

  • Predicting drug-induced liver injury (DILI) in preclinical stages is a significant challenge.
  • A need exists for human systems to study DILI mechanisms and individual drug susceptibility.

Purpose of the Study:

  • Establish a human liver organoid (HLO)-based screening model for DILI.
  • Analyze DILI pathology at the organoid level.
  • Develop a predictive model for drug toxicology.

Main Methods:

  • Generated reproducible HLOs from pluripotent stem cell lines with bile transport function.
  • Utilized qRT-PCR and single-cell RNA-seq to analyze hepatocyte transcriptomic state.
  • Developed a high-throughput imaging platform for HLO-based DILI assays.

Main Results:

  • HLOs exhibited polarized hepatocytes and bile canaliculi-like structures with unidirectional bile acid transport.
  • Single-cell RNA-seq revealed diverse hepatocytic populations mirroring primary hepatocytes.
  • The developed organoid-based toxicity screen (LoT) achieved high predictive values (Sensitivity: 88.7%, Specificity: 88.9%) for 238 drugs.

Conclusions:

  • The liver organoid-based Toxicity screen (LoT) is a promising system for liver toxicology.
  • LoT facilitates compound optimization, mechanistic studies, and drug screening.
  • This model supports precision medicine by predicting individual drug responses.
