Fig. 3From: ESC reverses epithelial mesenchymal transition induced by transforming growth factor-β via inhibition of Smad signal pathway in HepG2 liver cancer cellsESC reversed cell scattering induced by TGF-β in HepG2 cells. A Different concentration ESC (1–5 μg/mL) on cell scattering induced by TGF-β for 24 h. The magnification is ×200. B HepG2 cells treated with 5 μg/mL ESC for varying periods (2–6 h) prior to TGF-β addition. Vehicle (medium containing 0.2 % DMSO) was used to be as parallel control. The magnification is ×200. Note: c in this figure and other figures means vehicle controlBack to article page
