Figure 1: Immunohistochemical staining of FMNL3, E-cadherin, and Vimentin in clinical NPC and NPG samples.

FMNL3 expression in NPG cells (a), primary NPC cells (b) and metastatic NPC cells (c). E-cadherin expression in the epithelial cells of NPG samples (d), NPC tissues (e) and the metastatic samples (f). Cytosolic Vimentin protein expression in stromal cells, but not epithelial cells, of nasopharyngitis samples (g), and in some tumour cells of primary lesion of NPC (h) and the metastatic lesions (i). Left panels, NPG; middle panels, NPC primary lesions; right panels, NPC metastatic lesions. Scale bar, 60 μm.
