(A) Representative Western blot images and the corresponding bar graph of band densitometry showing increased expression of mesenchymal marker N-cadherin in HMECs in response to 1, 2.5 and 5 ng/ml of TGFβ1, TGFβ2, and TGFβ3 for 72 hours. (B) Representative Western blot images and the corresponding bar graph of band densitometry showing increased expression of the mesenchymal marker αSMA in HMECs in response to 1, 2.5 and 5 ng/ml of TGFβ1, TGFβ2, and TGFβ3 for 72 hours. Data are represented as mean ± SD. (n=3–5), *p<0.05.
