Syngeneic Mouse Model Services

Syngeneic Mouse Models (or allograft models) are the cornerstone of modern immuno-oncology (I-O). By engrafting murine tumor cells into immunocompetent mice of the same genetic background, these models provide a fully functional host immune system. Alfa Cytology offers a comprehensive suite of syngeneic models, optimized to support the development of checkpoint inhibitors, bispecific antibodies, and complex combination strategies with clinical-grade translatability.

Strategic Advantages in I-O Drug Development

Functional Tumor-Immune Interplay

Unlike xenografts, syngeneic models preserve the complete immune cascade—from antigen presentation to T-cell infiltration—making them essential for testing anti-PD-1/PD-L1, anti-CTLA-4, and cancer vaccines.

Quantitative Systems Pharmacology (QSP) Integration

We employ a unified QSP platform across core models (MC38, CT26, 4T1, B16F10). By capturing 12+ tumor-specific parameters and TIL (Tumor Infiltrating Lymphocyte) kinetics, we help partners validate biomarkers and optimize dosing strategies for clinical transition.

Complex Antibody Evaluation (Bispecifics & Beyond)

Our platforms, including humanized transgenic mouse strains (e.g., hCD3/hHER2), are specifically validated for evaluating bispecific antibodies (BsAbs). We provide data on T-cell activation and TME re-engineering to support the development of next-generation biologics.

Disease-Specific Pathological Backgrounds

Recognizing that patient health impacts drug response, we offer specialized models such as Obesity-Responsive TNBC models (C3-TAg in C57BL/6J). These allow for the study of how metabolic factors like obesity drive tumor progression and modulate immunotherapy efficacy.

Precision Methodology for Syngeneic Model Construction

Our construction methodology ensures high reproducibility and regulatory-grade data across all oncology indications:

Inoculum Standardization

All murine cell lines undergo strict STR profiling and pathogen screening to ensure consistent growth kinetics and a "clean" immune baseline.

Versatile Implantation Routes

We offer subcutaneous for rapid activity screening and orthotopic (intracranial, intrapulmonary, etc.) to better replicate the site-specific immune niche.

Deep Immunophenotyping

Utilizing multi-color flow cytometry and IHC to quantify CD8+ T cells, Tregs, and MDSCs, providing a granular view of drug-induced changes in the TME.

Ethically Rigorous Execution

All studies follow international 3Rs principles, delivering reproducible, audit-ready data that supports global regulatory submissions.
