Transforming growth factor β (TGFβ) induces epithelial–mesenchymal transition (EMT), which correlates with stemness and invasiveness. Mesenchymal–epithelial transition (MET) is induced by TGFβ withdrawal and correlates with metastatic colonization. Whether TGFβ promotes stemness and invasiveness simultaneously via EMT remains unclear. We established a breast cancer cell model expressing red fluorescent protein (RFP) under the E‐cadherin promoter. In 2D cultures, TGFβ induced EMT, generating RFPlow cells with a mesenchymal transcriptome, and regained RFP, with an epithelial transcriptome, after MET induced by TGFβ withdrawal. RFPlow cells generated robust mammospheres, with epithelio‐mesenchymal cell surface features. Mammospheres that were forced to adhere generated migratory cells, devoid of RFP, a phenotype which was inhibited by a TGFβ receptor kinase inhibitor. Further stimulation of RFPlow mammospheres with TGFβ suppressed the generation of motile cells, but enhanced mammosphere growth. Accordingly, mammary fat‐pad‐transplanted mammospheres, in the absence of exogenous TGFβ treatment, established lung metastases with evident MET (RFPhigh cells). In contrast, TGFβ‐treated mammospheres revealed high tumour‐initiating capacity, but limited metastatic potential. Thus, the biological context of partial EMT and MET allows TGFβ to differentiate between pro‐stemness and pro‐invasive phenotypes. Whether TGFβ promotes stemness and invasiveness simultaneously via epithelial‐mesenchymal transition (EMT) still remains unclear. Using a breast cancer cell model expressing red fluorescent protein under the E‐cadherin promoter, we demonstrate that the biological context of partial mesenchymal–epithelial transition (pMET) enriches mammospheres with invasive and pro‐metastatic potential. Sustained partial EMT under TGFβ enriches mammospheres with a pro‐stemness phenotype with higher tumour‐initiating potential.
