Regulation of the regenerative activity of dental pulp stem cells from exfoliated deciduous teeth (SHED) of children by TGF-β1 is associated with ALK5/Smad2, TAK1, p38 and MEK/ERK signaling

Figure 9. Effect of TGF-β1 on TIMP-1 and N-cadherin protein expression of cultured SHED. (A) TIMP-1 protein expression of SHED after exposure to TGF-β1 for 24 hours. (B) Effect of SB431542 on the TGF-β1-induced TIMP-1 expression of SHED. (C) Effect of 5z-7oxozeaenol on the TGF-β1-induced TIMP-1 expression of SHED. (D) N-cadherin protein expression of SHED after exposure to TGF-β1 for 24 hours. (E) Effect of SB431542 on the TGF-β1-induced N-cadherin expression of SHED. (F) Effect of 5z-7oxozeaenol on the TGF-β1-induced N-cadherin expression of SHED. One representative western blot picture was shown.
