High-Throughput Cardiotoxicity Screening Using Mature Human Induced Pluripotent Stem Cell-Derived Cardiomyocyte Monolayers

Executive Industry Relevance

Mature hiPSC-CM monolayers enable high-throughput, human-relevant cardiotoxicity screening, addressing a critical gap in predictive safety assessment for drug discovery portfolios. This platform increases translational confidence by recapitulating adult cardiac electrophysiology and contractility, supporting earlier and more reliable de-risking of candidate compounds. Integration of these matured systems into preclinical workflows reduces reliance on animal models and enhances decision-making at key inflection points in cardiovascular drug development.

Strategic Applications in Biopharma R&D

Early Discovery & Target Validation

• Enables interrogation of cardiac safety liabilities in human-relevant systems before animal studies.
• Supports mechanistic de-risking by modeling adult-like electrophysiological responses to candidate drugs.
• Facilitates functional target validation for cardiac ion channels and contractility pathways.

Screening & Assay Development

• Delivers standardized, mature hiPSC-CM monolayers for reproducible high-throughput screening.
• Enables quantitative measurement of voltage and calcium dynamics using optical mapping.
• Supports scalable assay formats compatible with 96-well plate platforms for compound evaluation.

Translational & Preclinical Research

• Aligns in vitro cardiac responses with clinical arrhythmia and cardiotoxicity endpoints.
• Provides continuity from early discovery through preclinical safety assessment using human-derived cells.
• Improves predictive value for translational biomarker development in cardiovascular research.
