If the tumor metastasizes into a major body cavity, either the abdomen, the chest cavity, or cranium, it can compromise respiration, digestion, urination, or defecation and, in some cases, locomotion. Syngeneic models are allografts immortalized from mouse cancer cell lines, which are then engrafted back into the same inbred immunocompetent mouse strain.

Animals with newly transplanted tumors may require only routine observation [3x/week according to BU policy] during the early stages of tumor development; however, animals in the terminal stages of tumor-associated disease or drug toxicity may require monitoring several times a day., The incidence and growth rate of spontaneous tumors, some chemically induced tumors, or those arising in transgenic animals may be difficult to predict. The presence of ulceration of the tumor is generally a criterion for euthanasia. . Due to the large tumor diameter and frequent tumor rupture, the experiment ended early on D37 . Kids can develop mouth ulcers just like adults. In general, the following sites should be avoided: The known biology and effects of any individual tumor model must be described in the animal use protocol, including expected clinical signs, anticipated moribundity/mortality, interventions for the relief of pain and suffering, and objective criteria for the assessment of humane endpoints.

More frequent observations may be necessary, possibly including on weekends and holidays, as determined by a veterinarian. This might even be when they have symptoms of cancer, for example, a lump in their breast. For human tumors, if an animal dies unexpectedly, show signs or symptoms of illness or tumor ulceration is observed, refer to the WSU IBC Memo: Reducing Biohazard Exposure Risks When Working with Human Cell Lines and Human Tissue in Animal Projects. padding: 10px 20px; Keywords.

Recent advances in the development of new methods of cancer immunotherapy require the production of complex cancer animal models that reliably reflect the complexity of the tumor and its microenvironment. Use of body condition scoring as an adjunct endpoint for tumor growth studies. The following information complements and supplements this document. Specifically, since there are differences in normal behavior between different mouse and rat strains, the responsible research staff must be familiar with the animal(s) on study BEFORE the experiment begins.
