Firstly, the epithelial character of bovine mammary epithelial cells was authenticated using immunofluorescence, then the cell grow curve was observed and investigated after S. vaccariae and T. mogono treatment. On the effect of S. vaccariae and T. mogono, cell adhesion molecules E-cadherin, β-catenin and CycinD1 mRNA and protein were detected by qRT-PCR and Western blotting, respectively. The results showed that the cellular keratin 18 expressed positively and proliferfated vigorously after S. vaccariae and T. mogono treament. The mRNA and protein levels of E-cadherin and CycinD1 were remarkably higher （P〈0.05） in 36 h after S. vaccariae and T. mogono treatment. The cell proliferation at 36 h was increased significantly （P〈0.05）. In conclusion, S. vaccariae and T. mogono have a positive impact on the cell proliferation and an effect on the adhesion molecules E-cadherin, β-catenin and CycinD1 in the Wnt signaling pathway.展开更多
