(A) Representative Western blot images and the corresponding bar graph of band densitometry showing reduced expression of endothelial marker eNOS 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 no significant change in the expression of endothelial receptor VE-cadherin 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.
