Fig. 2From: Buyang Huanwu Tang inhibits cellular epithelial-to-mesenchymal transition by inhibiting TGF-β1 activation of PI3K/Akt signaling pathway in pulmonary fibrosis model in vitroEffect of BYHWT on cell morphology in TGF-β1 treated A549 cells. A549 cells were incubated with TGF-β1 (10 ng/ml) with or without indicated concentrations of BYHWT for 24 h, followed by observation by a inverted phase contrast microscope (× 200 fold)Back to article page
