Evaluating tumor burden based exclusively on a percentage of body weight is generally not acceptable. Two of the main types of genes that play a role in cancer are oncogenes (genes that help cells grow) and tumor suppressor genes (genes that slow down cell division, repair DNA mistakes, or are involved in apoptosis)(4). Boston University Animal Science Center (BU ASC) recommends barrier housing for these animals whenever possible and monitoring for infectious disease.

Mice are good animals to create tumor models because they are low cost, have a short reproductive cycle, exhibit high tumor growth . Front. PC3 Xenograft Model - Altogen Labs 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.
