In vivo EMT reversion. A Fluorescence images and B the corresponding quantification of α-SMA-positive area of tumor sections in various formulation groups. C Masson’s trichrome staining images and D the corresponding quantification of collagen in various formulation groups. Immunohistochemical staining images and the corresponding quantification of E, F vimentin, G, H N-cadherin, I, J E-cadherin, and K, L snail in various formulation groups. All quantitative data are represented as mean ± SD, and quantified by 3 randomly selected observation fields using ImageJ software. Compared with the saline group, *P < 0.05, **P < 0.01, ***P < 0.001
