Stable HIF1α knockdown and Smad7 overexpression in hTSCs. mRNA levels of HIF1α (a) and Smad7 (b) were examined in hTSCs following their stable knockdown and overexpression, respectively. c Protein levels of both HIF1α and Smad7 were examined in hTSCs following stable knockdown of either HIF1α or Smad7, respectively. Data are shown as mean ± SD. Student’s t test was utilized for pairwise comparison. **p < 0.01, versus respective control
