Differential Post-Surgical Metastasis and Survival in SCID, NOD-SCID and NOD-SCID-IL-2Rγnull Mice with Parental and Subline Variants of Human Breast Cancer: Implications for Host Defense Mechanisms Regulating Metastasis

Abstract excerpt

We compare for the first time, the metastatic aggressiveness of the parental MDA-MB-231 breast cancer cell line and two luciferase-tagged in vivo-derived and selected pro-metastatic variants (LM2-4/luc⁺ and 164/8-1B/luc⁺ in SCID, NOD-SCID and NOD-SCID-IL-2Rγ(null) (NSG) mice following orthotopic implantation and primary tumour resection. The variants are known to be more aggressively metastatic in SCID mice,...
