Testing Immunotherapies in Syngeneic Models

Cancer immunotherapies are designed to work in conjunction with a patient's immune system to increase native anti-tumor responses. In this field of study, conventional xenograft models lack relevance due to the animals’ immunocompromised status. A syngeneic mouse model (e.g., 4T1 and MC38 cell lines), however, provides an effective approach for studying how cancer therapies perform in the presence of a functional immune system.

Syngeneic Mouse Models

In syngeneic mouse models (Allograft tumor systems) tumor tissue of the same genetic background is implanted into the mouse.

Syngeneic Mouse Models

Charles River offers a broad range of syngeneic mouse models with well-characterized responses to known immune checkpoint inhibitors (e.g., anti-PDL-1, anti-PD-1, anti-CTLA-4), immune profiling, and genetic evaluation (e.g., whole exome sequencing, RNA-seq). With a portfolio of syngeneic models that are responsive to immunotherapies as well complimentary in vitro and in vivo models in patient-derived xenografts (PDX), humanized models, and target validation, Charles River is your ideal partner to advance your immuno-oncology pipeline.

Syngeneic model selection is often based on:

  • Responsiveness to known immune-modulating therapies such as anti-CTLA-4 and anti-PD-1
  • Extent and composition of tumor-infiltrating leukocytes (TIL)
  • Immunogenicity

We offer syngeneic mouse models with and without profile. Our syngeneic models with profile have been evaluated for response with checkpoint inhibitors and/or chemotherapies. We also offer syngeneic models with growth curves, but no standard agent/checkpoint inhibitor data.

    * Note: Although these models have not yet been profiled for response to current standards of care, tumor growth curve data is available.

In addition pharmacological effects and pharmacokinetics of test compounds can be determined in the tumor microenvironment with high sensitivity and temporal resolution by our in vivo microdialysis services. In vivo implantable microdevices can also be used to aid studies by allowing simultaneous in vivo testing of multiple drugs, drug doses, or drug combinations in a single tumor.

Complementary Immunology Assays

As the science evolves, we have worked to enhance our portfolio with additional mouse models of cancer and will continue to expand into additional models that allow for this simulation in vitro and in vivo, including humanized models; genetically altered models; and cytokine response, T-cell activation, and toxicity assays.

Additionally we offer targeted transcriptomics using NanoString gene expression analysis platform to provide information on how therapeutic is regulating the tumor microenvironment.

Frequently Asked Questions (FAQs) on Syngeneic Mouse Models

  • What is a syngeneic mouse model?

    Syngeneic mouse models, also known as Allograft mouse tumor systems, consist of tumor tissues derived from the same genetic background as a given mouse strain. As the syngeneic mice retain intact immune systems, they are particularly relevant for studies of immunotherapies. Examples of uses include cancer therapies targeting immune checkpoint or immune co-stimulatory molecules.

  • What is an orthotopic model?

    In orthotopic models, tumors are implanted into the equivalent organ from which the cancer originated. Orthotopic models have a similar tumor microenvironment as the original tumor, which allows for the assessment of tumor development in a model that mimics natural disease progression.

  • What is a mouse xenograft model?

    In mouse xenograft models, human tumor cells are transplanted, either orthotopically or subcutaneously, into immune-compromised mice that will not reject the human cells. Xenograft mouse models allow for the analysis of human tumor response to anti-cancer therapies.

  • What is flow cytometry?

    Flow cytometry is an analytical cell-biology technique that utilizes light to count and profile cells in a heterogenous fluid mixture. Our in-house multiplex flow cytometry enables a comprehensive analysis of the immune system, allowing identification of various cell populations and deep interrogation of an immune response elicited from novel therapeutics.
