An In Vitro Model of Triple-Negative Breast Cancer

We have characterized two highly tumorigenic and metastatic basal B TNBC cell lines, XtMCF and LmMCF, with the additional values of having the normal and early-stage counterparts of them. This model allows the study of the evolution of TNBC, and investigates molecular pathways at different stages of transformation and progression in a relatively constant genetic background. This constitutes an ideal model for developing targeted therapy in two important fields in cancer biology which are the epithelial mesenchymal transition (EMT) and cancer stem cells (CSC).
