Advanced In Vitro Models for Drug Discovery
Physiologically Relevant In Vitro Models for Translational Drug Discovery
PozeSCAF develops advanced in vitro models that provide greater biological relevance than conventional two-dimensional cell culture systems. These models enable researchers to evaluate compound activity, mechanism of action, target engagement, efficacy, and safety within increasingly complex biological environments, helping improve confidence in early drug discovery decisions.
By selecting the most appropriate cellular model for each programme, our scientists generate experimental data that better reflects disease biology while supporting target validation, lead optimisation, and translational research.
Advanced In Vitro Model Expertise
Traditional biochemical and cell-based assays provide valuable information on target activity and cellular pharmacology. However, many therapeutic programmes require models that more closely reproduce tissue architecture, cellular interactions, and disease biology.
PozeSCAF supports the development and application of advanced in vitro models that increase biological relevance while remaining compatible with early-stage drug discovery workflows. Model selection is guided by the biological question, therapeutic indication, target mechanism, and experimental objectives rather than a one-size-fits-all approach.
Advanced In Vitro Model Capabilities
Three-Dimensional (3D) Cell Culture Models
Three-dimensional cell culture systems recreate aspects of native tissue architecture that cannot be achieved using conventional monolayer cultures. These models provide improved representation of cell morphology, cell-cell interactions, and microenvironmental responses.
Applications
- Compound efficacy evaluation
- Drug penetration studies
- Long-term treatment studies
- Cellular response profiling
- Target validation
- Mechanism-of-action studies
Multicellular Spheroid Models
Multicellular spheroids provide physiologically relevant tumour and tissue models that reproduce gradients of oxygen, nutrients, and therapeutic exposure. These systems support evaluation of compound penetration, efficacy, and cellular responses within three-dimensional structures.
Applications
- Oncology drug discovery
- Anti-tumour efficacy studies
- Drug penetration assessment
- Resistance mechanism studies
- Combination therapy evaluation
- Lead optimisation
Organoid Models (Where Applicable)
Organoid systems provide complex three-dimensional cellular organisation derived from tissue-specific cells. When appropriate for programme requirements, organoid models may provide additional biological insight beyond conventional cell culture by more closely representing tissue physiology and disease characteristics.
Applications
- Disease modelling
- Functional pharmacology
- Translational biology
- Candidate prioritisation
- Mechanistic studies
Co-Culture Systems
Co-culture models enable investigation of interactions between multiple cell populations involved in disease progression and therapeutic response. These systems can improve understanding of cell-cell communication, target biology, and compound activity within more complex biological environments.
- Tumour–stromal interactions
- Immune-oncology research
- Fibrosis biology
- Inflammatory signalling
- Mechanistic studies
Primary Cell Models
Primary cells provide experimentally relevant systems that preserve many characteristics of native tissues. These models support confirmation of biological findings obtained in immortalised cell lines while improving confidence in translational relevance.
Applications
- Target validation
- Mechanism-of-action studies
- Toxicity assessment
- Functional biology
- Translational confirmation
Selecting the Right Biological Model
Selecting an appropriate experimental model is critical for generating meaningful biological data. Our scientists evaluate multiple factors before recommending an assay system, including:
- Biological target
- Disease mechanism
- Target expression
- Cellular phenotype
- Experimental endpoint
- Required throughput
- Translational relevance
- Project timeline
This scientific approach ensures that model complexity is aligned with programme objectives while maintaining experimental reproducibility and efficient project execution.
Why Advanced In Vitro Models Matter
More biologically relevant experimental systems can improve understanding of compound behaviour before progressing to in vivo studies. By incorporating greater physiological complexity, advanced in vitro models help scientists investigate target biology, evaluate pharmacological responses, identify potential liabilities, and generate higher-confidence data for programme progression.
Advantages
- Improved physiological relevance
- Better prediction of compound responses
- Enhanced understanding of disease biology
- More representative cellular microenvironments
- Improved confidence during lead optimisation
- Support for translational decision-making
