Effects of OA on TGF-β1-induced Morphological changes in NRK-52E cells. The cells were incubated with 5 ng/mL of TGF-β1 for 48 h with different concentrations of OA (0, 2, 4, 8 μM). a Untreated NRK-52E cells showed a pebble-like shape is clearly observed. b TGF-β1-treated cells showed a more elongated morphological shape. c, d, e showed OA reversed TGF-β1-induced morphological changes (Magnification of 200×)
