What is syngeneic model?

Updated on April 03, 2026
Syngeneic models are allografts immortalized from mouse cancer cell lines, which are then engrafted back into the same inbred immunocompetent mouse strain. The identical host and cell line strain means that tumor rejection doesn’t occur, creating an immunocompetent model for immunotherapy assessment.
What are murine tumor models?
Xenograft Mouse Models
| Disease | Cell Line | Mouse Strain |
|---|---|---|
| Colorectal cancer | COLO-205, HT29, HCT116, Caco-2, RKO | Nude |
| Breast cancer | MCF-7, T47D, MDA-MB-231 | Nude, SCID |
| Prostate cancer | PC-3, DU-145 | Nude |
| Ovarian cancer | OVCAR-3, OVCAR-5 | Nude, SCID |
What is orthotopic model?
Orthotopic models involve the seeding of tumor cell lines into the corresponding tissue in animal models. This strategy allows us to assess tumor development in a relevant environment and evaluate efficacy in a preclinical tumor model that mimics the disease process in humans.
What is syngeneic tumor 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.
What do I do if my mouse has a tumor?
Lumps and bumps on or under the skin are relatively common in rats and mice. Sometimes these masses can occur suddenly and grow quite quickly and other times they grow slowly over time. In any case, it is recommended to book in for a vet check as soon as you notice a lump on your pet mouse or rat.
What is a tumor model?
Listen to pronunciation. (TOO-mer MAH-dul) Cells, tissues, or animals used to study the development and progression of cancer, and to test new treatments before they are given to humans. Animals with transplanted human tumors or other tissues are called xenograft models.
What is xenograft model?
In human tumor xenograft models, human tumor cells, collected by biopsy or cultured from a known cell line, are transplanted into immunocompromised mice that do not reject human cells, either under the skin (ectopic model) or into the organ type from which the tissue originated (orthotopic model).
How do I build a PDX model?
The PDX model can be developed by the implantation of cancerous tissue from a patient’s tumor into an immune-deficient mouse directly, thereby it preserves both cell-cell interactions and tumor microenvironment.
What are PDX and CDX lines?
Patient-Derived Xenograft (PDX): Immunodeficient animals are engrafted with human-derived tumor tissue. Cell Line Xenograft (CDX): Immunodeficient animals are engrafted with human tumor cell lines.
