A predictive in vitro risk assessment platform for pro-arrhythmic toxicity using human 3D cardiac microtissues
Research Overview
Predicting whether a drug, industrial chemical, or environmental toxicant can trigger arrhythmia or sudden cardiac death is a central problem in safety science, and existing approaches lean on single ion channels, non-human species, or models with limited physiological translation. This study advanced a human-relevant alternative: 3D cardiac microtissues built from human iPSC-derived cardiomyocytes together with human cardiac fibroblasts.
Using automated algorithms and statistical analysis of eight complementary metrics of the cardiac action potential, the team showed that these engineered human microtissues support robust, reproducible pro-arrhythmic cardiotoxicity assessment — moving in vitro risk evaluation closer to direct human physiological relevance.
