The concern of size for individual tumors is related to central necrosis, Ulceration of skin overlying tumors, and abrasions. Mice and rats have been models of choice for a long time, and even more since the development of genetically engineered models (GEMs). . You should especially do so if you have any new symptoms, such as unexplained skin lumps or sores. Animals with ulcerated tumors must be monitored daily including weekends and . Tumor-bearing animals exhibiting any of these signs should be euthanized based on severity of clinical signs: 1. Front. As soon as a tumor has ulcerated, the growth pattern will alter, which may be sufficient grounds for terminating the experiment. However, only a portion of the tumor growth data was recorded and presented in thegures and elucidated in the legends. } (1) KPC mice develop a spectrum of premalignant lesions called Pancreatic Intraepithelial Neoplasia (PanINs) that ultimately . Thus, the BCS becomes an important assessment tool in the tumor load experiments. background-color: #eee; This guidance assumes a normally sized adult rodent (a ~25 g mouse or a 250 g rat). (5)Fusion genes in solid tumors: an emerging target for cancer diagnosis and treatment Please note that the limitation on any single tumor (2.0 cm diameter in mice and 4.0 cm in rats) will still be valid.
