Redgate ES, Deutsch M, Boggs SS. Our laboratory utilizes a variety of genetically engineered mouse models of pancreatic cancer. .metaslider .flexslider { For subcutaneous tumors the maximum allowable size is 20 mm in diameter for a mouse or 40 mm diameter for a rat.2 If the animal is host to more than one tumor, this size is the maximum allowable size for all tumors combined. Unexplained weight loss is often one of the first noticeable symptoms of cancers. Tumor Size and Location .entry-meta, article.page .entry-header .entry-meta { d. Monitoring 1. } The allowable sizes of tumors will be decreased if the tumors are injected into immature or genetically small mice. 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. Cancer. This is intended to facilitate communication between the research laboratory and the Center for Animal Research and Education (CARE) staff and veterinarians. 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. During the terminal phase, the animals should be inspected and continually assessed for early termination several times each day [daily according to BU policy]. 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. mouse tumor ulceration - marglass.ro If ulceration .
