Relationship between α-SMA actin fiber localization in fetal mice cells and wound stimulation.

(A) Altered α-SMA distribution in dermal and fascial fibroblasts at various developmental stages in response to TGF-β1 stimulation. Scale bar = 20 mm. Red and green fluorescence signals correspond to α-SMA and actin, respectively. (C) α-SMA distribution and actin expression in E13 dermal and E17 fascial fibroblasts in the scratch assay. Scale bar = 10 mm. Red, green, white, and blue fluorescence signals correspond to α-SMA, phalloidin (actin), plasma membrane, and DAPI (nucleus), respectively.
