TGFβ1 and BMP7 exhibited some common and some drastically different responses based on the analysis of expression of mesenchymal (fibronectin and vimentin), epithelial (E‐cadherin and RFP), EMT transcription factor (ZEB1) and breast cancer stem cell (CD44 and Sox2) proteins under the same 3D culture conditions after stimulation for 3 and 7 days (Fig. 3D). The gene discussed is TGFB1; the disease is breast carcinoma.
