Why Multi-Organ Matters
Drugs don't act on isolated organs. They circulate through the entire body, are metabolized by the liver, excreted by the kidneys, and can affect distant organs in unexpected ways. Single-organ models miss these critical systemic interactions that often cause clinical trial failures.
Integrated Organ Systems
Liver
Central metabolic hub processing drugs via CYP450 enzymes. Critical for understanding drug metabolism, DDIs, and hepatotoxicity.
Kidney
Primary excretion organ filtering metabolites. Essential for understanding drug clearance, nephrotoxicity, and renal dosing.
Heart
Cardiac tissue models measuring contractility and electrophysiology. Critical for detecting QT prolongation and cardiotoxicity.
Lung
Air-blood barrier models for inhalation drugs and pulmonary toxicity. Includes mechanical breathing motion.
Brain
Blood-brain barrier and neural tissue for CNS drug delivery and neurotoxicity. Critical for neurotherapeutics.
Gut
Intestinal epithelium for oral drug absorption and first-pass metabolism. Includes microbiome interactions.
Integration Approaches
Physical Coupling
Microfluidic channels physically connect organ compartments, allowing media to flow between tissues and carry secreted factors, metabolites, and drugs.
- Realistic flow dynamics
- Organ crosstalk via secreted factors
- Metabolite exchange
Media Transfer
Conditioned media from one organ model is transferred to downstream organs, simulating systemic circulation without physical connection.
- Flexible timing protocols
- Compatible with varied culture systems
- Scalable to high-throughput
Computational Coupling
Digital twins link experimental data from individual organ models, using PBPK modeling to simulate systemic distribution and interaction.
- Infinite scalability
- What-if scenario testing
- Virtual population generation
Key Applications
Drug-Drug Interactions
Identify metabolic interactions between co-administered drugs mediated by shared CYP enzymes or transporters.
First-Pass Metabolism
Model gut-liver axis to predict oral bioavailability and the impact of hepatic extraction.
Secondary Organ Toxicity
Detect toxicity in distant organs caused by metabolites generated in the liver or other tissues.
CNS Drug Delivery
Evaluate BBB penetration after systemic administration including the effects of peripheral metabolism.
