3D Tumor Model Screens in Clonogenic Assays
In conjunction with our drug sensitivity and molecular characterization data, our 3D Tumor Models, done by using our proprietary patient-derived xenograft (PDX Model) explants or cell line derived xenografts (CDX Models), enable you to evaluate the potency of your compound compared to standard-of-care drugs. This allows you to identify the most promising drug candidates, tumor histotypes and molecular subtypes for further testing.
A High-Content Image Analysis Approach for Quantitative Measurements of Chemosensitivity in Patient-Derived Tumor Microtissues

PDX Models and Combination Studies
Data collected in 3D Tumor Models can then be used to select PDX models for subsequent in vivo efficacy tests. The data can also be used to run systematic two-drug combination therapy studies over a range of concentrations and to correlate the tumor response with molecular data (biomarker identification).
Integrating In Vitro and In Vivo PDX Models
Our fully integrated approach using in vitro 2D and ex vivo 3D Tumor Models with in vivo PDX models and bioinformatics data will facilitate drug development and enhance the speed of your oncology research.

Frequently Asked Questions (FAQs) in PDX Model Research
What is a patient derived xenograft?
Patient derived xenografts (PDX) are models of cancer where the tissue or cells from a patient’s tumor are implanted into an immune deficient or humanized mouse. PDX models simulate human tumor biology allowing for natural cancer progression, and offer the most translational research model for evaluating efficacy. Determine which PDX model is best for your studies
Does in vitro data correlate with in vivo PDX models?
Data collected in in vitro models can be used to select PDX models for subsequent in vivo efficacy studies. Review the data
What is a Clonogenic Assay?
Clonogenic assays can be used to determine cell reproductive death after treatment with radiation and other cytotoxic agents. This technique allows you to study the effectiveness of specific agents on the survival and proliferation of cells.
