PDX FAQs
Patient-derived xenograft (PDX) models are cutting-edge tools in oncology research, derived from transplanting patient tumor tissues directly into immunocompromised mice. These models preserve the genetic, histological, molecular and spatial characteristics of the original human tumors including intratumor heterogeneity, offering a highly relevant platform for preclinical drug testing.
- Clinical relevance: PDX models closely mimic human tumors, including tumor heterogeneity, providing a superior model compared to traditional cell lines or genetically engineered models
- Predictive power: PDX models predict patient responses to therapies more accurately than other models, enabling researchers to prioritize drug candidates with higher potential for clinical success
- Personalized medicine: Each PDX model is derived from a specific patient's tumor, allowing for testing of therapies tailored to individual genetic and molecular profiles
- Study of resistance mechanisms: PDX models facilitate the study of drug resistance mechanisms by enabling longitudinal studies of tumor progression and response to treatment over time
- Long-term stability: PDX models can be passaged through multiple generations while maintaining the genetic and phenotypic stability of the original tumor, supporting longitudinal studies and reproducible results
Standard use includes, but is not limited to:
- Preclinical evaluation of novel therapies (including cell therapy)
- Validating novel drug combinations
- Screening drug-sensitive patients (personalized medicine)
- Exploring drug response/resistance mechanisms
- Biomarker evaluation
