Figure 3From: Epigallocathechin gallate, polyphenol present in green tea, inhibits stem-like characteristics and epithelial-mesenchymal transition in nasopharyngeal cancer cell lines Effect of EGCG on NPC cell proliferation. EGCG had effects on cell proliferation and induced growth inhibition of NPC parental and sphere-derived cell in a concentration dependent manner. However, sphere-derived cells showed relative resistance to EGCG (μM) compared to parental cells. (A) MTT assay and (B) BrdU assay. Both assays showed similar results.Back to article page
