Humanized mouse models are beneficial tools for immuno-oncology and infectious disease research. They have improved the ability to predict human responses to new therapeutics in clinical development.

When your research requires humanized animal models, Charles River offers multiple options, both founded on the NCG triple-immunodeficient mouse.

•   CD34+ Humanized Mouse Model
•   PBMC Humanized Mouse Model
•   NCG/PBMC Select Humanization Kit



Research Models and Services

Genetically Engineered Models and Services (GEMS) 
Our GEMS division offers a wide variety of services from breeding to model creation. Our decades of experience and vast network of vivariums around the world gives us the opportunity to offer an unparalleled selection of custom models and services to meet your unique needs. Researchers at Columbia receive many discounts off services provided by GEMS. Use our quoting tool to view the best price for your study.

Model Creation Services
Our experts can guide you through the model creation process.

Embryology Services
Our embryology services will help you protect your lines and generate new ones. 
•   Our cryopreservation services can protect your lines from genetic drift, natural disasters, and catastrophic events.
•   Rederivation can help you obtain animals that are free of infectious agents.   
•   Rapid colony development uses sophisticated IVF technology to generate animal colonies quickly.

Animal Model Evaluation
Select the right animal model for your study by trialing our free model evaluation program. Reduce risk by assessing the quality of our models on your own terms and at no cost.

Oncology Services

•   Chemistry services
By working with our chemists right from the beginning, you can optimize the best version of your compound.

•   In vitro cell biology assays
2D and 3D cell assays using patient-derived materials and the cells of the tumor microenvironment allow us to accurately model human cancers.

•   Predictive immunotoxicology
Assays and models to mitigate risk of progressing your drug.

•   In vivo pharmacodynamic screening model
To allow the function of a therapeutic to be examined before entering a disease-specific model.

•   In vivo oncology efficacy models
You can test your drug in fully characterized patient-derived xenografts in our custom humanized models, with the option to implant as orthoptopic models for greater disease relevance, to truly represent the human disease state.

•   Oncology analysis
Ex vivo services, such as tumor microdialysis, sample the tumor microenvironment to further aid in your decision making.

•   Safety assessment and toxicology
Our extensive regulatory knowledge aids translation to the clinic, which is especially important for cell and gene therapies where discovery and safety studies will be closely linked.
