Executive Industry Relevance

Long-term ex vivo cultivation of human myocardial tissue slices enables direct functional assessment of cardiac contractility under near-physiological conditions. This platform supports predictive evaluation of pharmacological effects and mechanistic de-risking in early cardiovascular drug discovery. The approach enhances translational continuity by bridging in vitro findings with human tissue-level responses, informing portfolio decisions in preclinical R&D.

Strategic Applications in Biopharma R&D

Early Discovery & Target Validation

• Enables interrogation of cardiac contractile mechanisms in human tissue context.
• Supports functional target validation by quantifying drug-induced changes in contraction parameters.
• Facilitates mechanistic de-risking for cardiovascular targets prior to in vivo studies.

Screening & Assay Development

• Provides a reproducible, biomimetic system for compound screening on human myocardial slices.
• Delivers quantitative outputs such as force-frequency relation and stimulation threshold for assay standardization.
• Allows real-time monitoring and recording of contractile responses to pharmacological agents.

Translational & Preclinical Research

• Aligns ex vivo functional data with disease-relevant human cardiac physiology.
• Enables assessment of therapeutic and cardiotoxic effects in a preclinical human tissue model.
• Supports risk-adjusted advancement decisions by providing predictive human data prior to animal studies.
