Fig 3From: Short-term stimulation with histone deacetylase inhibitor trichostatin a induces epithelial-mesenchymal transition in nasopharyngeal carcinoma cells without increasing cell invasion abilityMorphology of NPC cells treated with TSA. CNE2 and C666–1 cells were treated with 0 and 200 ng/ml TSA for 0, 24 and 48 h, and then cells were photographed under inverted microscope. Scale bars = 200 μm or 100 μmBack to article page
