Figure 3. Immunofluorescence staining for PanCK, KLF4, and vimentin in human colonic tissues. Representative images of normal adjacent mucosa (SB474N) show that KLF4 and vimentin do not co-localize (top inset) and tumor sections (SB474T) that show loss of KLF4 and stain of vimentin in epithelial cells. White boxes mark insets. White arrowheads indicate vimentin stain within epithelial cells (bottom inset). Scale bar: 50 μm
