Figure 9From: TGF-β1 and serum both stimulate contraction but differentially affect apoptosis in 3D collagen gelsWestern blot for selected pro- and anti-apoptotic proteins in HFL-1 cells treated with Smad3. Collagen gels made from Smad siRNA cells and control siRNA cells were digested, cells were collected, lysed and the cell lysate were evaluated by Western blot. Data presented are from one representative experiment repeated twice.Back to article page
