Lack of tumorigenesis and protumorigenic activity of human - BMC Cancer Institutional Animal Care and Use Committee (IACUC): Rodent Tumor manually restrained mouse using MRI. When the average . Tumor Size and Location 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. 6N! 2018;9:259. doi: 10.3389/fphar.2018.00259.
