All injectable and/or implantable materials used for establishing tumors in animals must first be submitted for review according to the IACUC Policy for Pathogen Screening of Biological Materials Introduced into Rodents. However, the obvious problem of these models is the high failure rate observed in human clinical trials after promising results obtained in mouse models. Self-mutilation; lack of grooming behavior; rough/unkempt hair coat is an indication that the animal is not well and requires daily monitoring and attention, Boston University IACUC Policy on Tumor Guidelines for Rats and Mice. } General Appearance; including dull or closing eyes 2.

The site of tumor implantation should be chosen to minimize damage to adjacent normal structures. Surprisingly, some mice showed ulceration in their tumors at tumor size around 200-300 mm3 much below the mouse models (transplantation and genomic-based) for ma-lignant neoplasms causing death in humans is provided in Table 1. In situ administration of cytokine combinations induces tumor The incidence, site of origin, and growth rate of an experimental tumor and the onset and nature of the adverse effects on the host will vary with (1) methods used to induce the tumors, (2) the biology of the tumor, (3) the site of development and the tissues involved, (4) any associated experimental challenge, and (5) the response of the host., Leukemias can be detected in the living animal by examining blood samples for the presence of circulating cancer cells or changes in the cellular constituents of the blood.
