Figure 6From: Effects of PPARγ ligands on TGF-β1-induced epithelial-mesenchymal transition in alveolar epithelial cellsRegulation of TGF-β1-induced changes in cell morphology by rosiglitazone. A549 cells were incubated with vehicle (0.1% DMSO), TGF-β1 (0.25 ng/ml), TGF-β1 (2.5 ng/ml) or TGF-β1 (2.5 ng/ml) + RGZ (10 μM) for 72 hr and photographed at 100× magnification. The images are representative of 4 separate experiments.Back to article page
