Digital Twins for Microphysiological Systems: MPSlabs
Microphysiological systems (MPS) and organ-on-chips (OoC) aim to represent human physiology in vitro more appropriately than animals. Their biggest potential is the early prediction of clinical outcomes by identifying human-specific safety risks and lack of efficacy, yet they are still not routinely used in drug development.
Regulatory momentum is increasingly welcoming new approach methodologies (NAMs), including cell-based assays and computational models, alongside ongoing efforts to reduce unnecessary animal testing. At the same time, many candidates that look promising preclinically still fail to translate clinically highlighting the need for more human-relevant, quantitative decision support.
At MPSlabs, we provide a virtual testing center for microphysiological systems, organ-on-chips, and 3D organoids/spheroids. The center enables pharmaceutical, crop science, agro, and other chemical companies and operators to predict the distribution of compounds in humans precisely and accurately, without animals.
We focus on harnessing advanced in vitro systems to quantify human pharmacokinetics (ADME). We integrate quantitative data from existing MPS/OoC experiments into our digital twin platform, a modeling environment that combines hardware specifications, physiological processes, and compound-specific properties to simulate in vitro and in vivo behaviors. Rather than developing or running physical chips ourselves, we translate MPS outputs into predictive, human-relevant insights by mapping biological processes onto mathematical equations. This enables us to estimate ADME-related parameters, optimize experimental designs, and classify compounds for toxicity or efficacy.
A recent focus also includes applying AI/ML to multi-omics data such as genomic fingerprints from patient-derived tumor organoids (PDOs) to prioritize candidates for downstream wet-lab validation in collaboration with experimental partners.
As a dedicated business unit of ESQlabs, our results support improved translational and predictive accuracy of MPS/OoC as alternatives to animal in vivo models.
What we can offer
At MPSlabs, we’ve distilled our capabilities into three complementary service areas. You can leverage any one of them independently, or combine them into a fully integrated solution tailored to your specific goals, data availability, and workflow.
Operational Design
We help you plan and structure MPS/OoC studies so they generate quantitative, decision-ready data. This includes optimizing set-ups and sampling strategies, defining the context-of-use, and building cost- and time-efficient study plans that support robust interpretation and downstream modeling.
Digital Twin Integration
We integrate your MPS/OoC readouts into our digital twin framework by combining experimental outputs with system specifications, physiological processes, and compound properties. This enables translation toward human PK/ADME, supports scenario simulations (e.g., drug–drug interactions or special populations), and strengthens confidence in exposure- and safety-relevant decisions.
Predictive AI/ML Insights
When multi-omics or organoid-derived data are available, we apply AI/ML approaches in combination with digital twin outputs to extract predictive signals early. This supports prioritization of candidates, earlier identification of potential toxic liabilities, and more patient-specific predictions for precision medicine use cases.
Whether you choose a single focus area or engage all three, our mission remains the same: to push boundaries in MPS/OoC research, empower data-driven innovation, and ultimately help replace animal testing through more human-relevant models.
Our Virtual Testing Center
MPSlabs offers the world-first Virtual Testing Center for microphysiological systems, organ-on-chips, and 3D organoids/spheroids. The center enables chip manufacturers and operators to predict the distribution of compounds precisely and accurately in humans – all without animals.
