Immunofluorescence of epithelial and mesenchymal markers, EMT-related transcription factors and F-actin. (A) Confocal microscopy analysis of Bel-7402 cells co-clutured with RF/6A cells for 72Â days. (B) Confocal microscopy analysis of Bel-7402 cells co-clutured with HL-7702 cells for 60Â days. The green signal represents corresponding protein staining and the red signal indicates nuclear DNA staining by propidium iodide (PI).
