Tumor Guidelines for Mice and Rats. (PDF file) , 12/14/2022 REVISED. Body Condition Scoring (see BCS sheet below(10)) are routinely used to monitor the animals welfare. Low-level whole body irradiation or immunosuppressive agents are frequently used to further suppress the immune response of immunodeficient rodents before inoculation with human tumor xenografts. Thus, the BCS becomes an important assessment tool in the tumor load experiments. (5)Fusion genes in solid tumors: an emerging target for cancer diagnosis and treatment Ulcerated or necrotic tissue may result in a continuous seepage of body fluids and predisposes to infection. window.lsow_fs = {can_use_premium_code: false}; b.

An animal in chronic pain or distress that can not be relieved by analgesics must be euthanized unless prior scientific justification for these humane endpoints are approved by the IACUC. Pick your mouse up and turn it over to begin the visual inspection. 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. .widget { background-color: #eee; In the live animal, this has to be estimated, since the tumor cannot be weighed apart from the host.

It can then break through the skin and cause an open sore (or ulcer) on the skin surface. Any evidence of lethargy or other change in behavior, change in ambulation, diarrhea, neurological signs (e.g., circling, head tilt), or increased respiratory effort must be reported to the veterinary staff. (1) KPC mice develop a spectrum of premalignant lesions called Pancreatic Intraepithelial Neoplasia (PanINs) that ultimately . In general, the more severely immunocompromised a mouse host, the more likely it is that tumor cell line or primary tumor will grow. vertical-align: -0.1em !important; Ulceration of a tumor typically requires euthanasia unless Ulceration without euthanasia is justified in the animal use protocol and in consultation with a veterinarian. 4.
