Syngeneic Mouse Models

Custom-made solutions and validated tumor models to accelerate your oncology research.

Syngeneic tumor models are an essential part of preclinical immunotherapy research. But with limited data and without an exact-match tumor model your research aspirations can become stunted.

Melior creates customized models and experiments that meet your needs. When you partner with Melior you can confidently and efficiently perform in vivo efficacy evaluations of potential cancer therapies. These include targeted therapy, cytotoxic drugs, antibody therapies, checkpoint inhibitors and gene therapies.

Secure early access to the right model and get data that pushes your oncology R&D forward.

Confidently test your immunotherapeutic agents and combination therapies with syngeneic tumor models

Because syngeneic mouse tumors are immunologically compatible with their host, tumor transplantation does not provoke an immune response. Instead, tumors grow within an intact immune system. This system provides valuable models for studying therapies that act on the host immune system. With Melior’s syngeneic mouse tumor models, you can develop cancer therapies that work together with the immune system to reduce and reverse tumor growth, as with checkpoint inhibitors.

Advantages of using syngeneic tumor models

  • Explore cancer immunotherapies: Get relevant data and better understand the mechanisms of action of new therapeutics targeting immune cell interactions.
  • Leverage models with fully competent immunity: Enable studies on the interaction between tumor cells, immune cells, microcroenvironment, and microbiome
  • Benefit from simple, cost-saving solutions: Generate reliable results with animals inherently less expensive than xenograft models

Data Highlight: Checkpoint Inhibitors and Taxanes

Immune Checkpoint Inhibitor and Chemotherapy Validation in CT26.WT Tumor Model.
1 x106 CT26.WT mouse colon cancer cells were subcutaneously injected into the rear flank of Balb/c mice. Once mean tumor size reached 100-150mm3, mice were randomized into groups and treated with vehicle, anti-PD-1 antibody (12.5 mg/kg IP) once per week, or paclitaxel (20 mg/kg IP) once per week. Tumor growth volume was monitored at baseline and at days 4, 7 and 11, following initiation of treatment, using calipers. Both the anti-PD1 group and paclitaxel group showed significant difference compared with untreated group (both p<0.001; Data area mean ± SEM; n=6 for Vehicle and anti-PD-1; n=4 for paclitaxel).

Immune Checkpoint Inhibitor and Chemotherapy Validation in WEHI164 Tumor Model.
1 x106 WEHI164 mouse fibrosarcoma cells were subcutaneously injected into the rear flank of Balb/c mice. Once mean tumor size reached ~150mm3, mice were randomized into groups and treated with vehicle anti-PD-1 antibody (12.5 mg/kg IP) once per week, or paclitaxel (20 mg/kg IP) once per week. Tumor growth volume was monitored at twice per week using calipers. Anti-PD1 significantly inhibited tumor growing. Both the anti-PD1 group and the paclitaxel group showed significant differences compared with the untreated group (both p<0.001; Data area mean ± SEM; n=5 for each group).

Subcutaneous Models vs Orthotopic Models

Standard subcutaneous models are an efficient choice for measuring tumor response to a new drug. This method involves implanting tumor cells into the flank of a mouse and monitoring growth. Tumors grow efficiently in this model. It allows for analyses such as drug efficacy and endpoint analyses, including survival, flow cytometry, expression analysis, histology, and more.

Orthotopic models, on the other hand, involve seeding tumor cell lines into the corresponding mouse tissue. This strategy assesses tumor development in a relevant tissue environment that mimics the disease process in humans. With orthotopic models, we can monitor and more accurately quantify primary tumor growth, metastatic activity, and response to therapy.

Are syngeneic tumor models right for you?

A syngeneic tumor model only applies to rodent-derived tumors because it relies on the animals’ immune system to remain intact. If you need human-derived tumors, or your cancer type is not available in a syngeneic mouse model, you may want to consider our xenograft models.

Xenograft models offer a wider range of cancer types and produce data that may be more readily translatable to human studies.
