We explored whether IL-6-induced EMT promoted the generation of breast cancer stem-like cells (BrCSCs) in epithelial-like breast cancer cells, and whether the cytokines EGF and bFGF, analogous to IL-6, per se induced epithelial-mesenchymal transition, resulting in the enrichment of BrCSCs in mammosphere cultures. Here, FGF2 is linked to breast carcinoma.
