Tumor Ulceration Ulceration (overt open lesion or scabbed area) of a tumor does not necessarily require euthanasia, but Mice are good animals to create tumor models because they are low cost, have a short reproductive cycle, exhibit high tumor growth . In our previous blog, we described the three types of models to be used for xenografts (immunocompromised, humanized and PDX). Boston University Animal Science Center (BU ASC) recommends barrier housing for these animals whenever possible and monitoring for infectious disease.

However, those models can have some limitations: many of those studies use immunocompromised mice, with a subcutaneous implantation of the tumor tissue, which prevent immune responses and site specific interactions (3), thereby losing crucial features of the tumor microenvironment. However, to stay in alignment with the 3R principles (Replace, Reduce, Refine) (1), which providea framework for performing more humane animal research, it is our legal and ethical obligation as researchers, veterinarians and animal caretakers to use methods which minimizeanimal suffering and improve their health and welfare. Naturally occurring tumors or masses are also found in laboratory rodents, as well as in other animals, including humans.

Standard endpoints can be based on the indicators below, and used to develop a scoring system: Additional endpoints specificto cancer models (suchas tumor size, tumor ulceration, ability to ambulate) or specific to the known pathology of the particular model used, can also be taken into account(12, 13). In the absence of reliable laboratory-based assays, animals with leukemia or lymphomas should be observed for early clinical signs such as anemia, loss of condition or weight, and enlargement of the spleen and lymph nodes. This evaluation may be made either by mouse antibody production (MAP) testing or by polymerase chain reaction testing (PCR) at an approved contracted organization.
