Epithelial-Mesenchymal Plasticity Determines Estrogen Receptor Positive Breast Cancer Dormancy and Epithelial Reconversion Drives Recurrence

The authors compare intraductal xenografts of ER+ and TNBC cells and demonstrate that disseminated TNBC cells proliferate similarly as TNBC cells at the primary site, whereas disseminated ER+ breast cancer cells proliferate slower.
