Figure 1. TGFβ induce ETM in hSAECs. (A) Imaging to show the cell phenotype change after EMT.
The fixed hSAECs (upper panel) and EMT-hSAECs (low-panel) were stained with phalloidin-FITC for F-actin and DAPI for nuclei (magnify x122). (B) Gene expression level of EMT transcription factors (SNAI1, ZEB1 and TWIST1) by RT-qPCR.
