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 8. Effect of TGF-β1 on the ALP activities of cultured SHED as analyzed by ALP enzyme activity assay. (A) Quantitative ALP enzyme activity assay of SHED with/without exposure to TGF-β1 for 5 days. (B) Effect of SB431542 on the TGF-β1-induced increase or decrease in ALP activity of SHED. (C) Effect of 5z-7oxozeaenol on the TGF-β1-induced increase or decrease in ALP activity of SHED. (D) Effect of U0126 on the TGF-β1-induced increase or decrease in ALP activity of SHED, (E) Effect of SB203580 on the TGF-β1-induced increase or decrease in ALP activity of SHED. *Denotes statistically significant difference when compared with respective control group. #Denotes statistically significant difference when compared with respective TGF-β1-treated group.
