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 3. Effect of TGF-β1 on the morphology of SHED. (A) Control SHED, exposure to (B) 0.1 ng/ml TGF-β1, (C) 0.5 ng/ml TGF-β1, (D) 1 ng/ml TGF-β1, (E) 5 ng/ml TGF-β1 and (F) 10 ng/ml TGF-β1 for 5 days. One representative morphologic picture of cells was shown.
