Epithelial-mesenchymal transition is induced by SDF-1 and inhibited by AMD3100 and DKK-1 in vitro. (A) WB demonstrated that the expression levels of α-SMA were increased and those of E-cadherin were reduced in the SDF-1 group, and these alterations were inhibited by AMD3100 and DKK-1, respectively. (B) Grayscale analysis of the WB. (C) Reverse transcription-quantitative polymerase chain reaction analysis revealed that the mRNA expression levels of α-SMA and E-cadherin corresponded to the results of the WB. (D) Quantitative analysis of the wound healing assay. (E) Representative images of the wound healing assay of the cells in the different groups at 0, 12 and 24 h post-scratching. *P<0.05 and **P<0.01 vs. control. SDF-1, stromal cell-derived factor 1; WB, western blotting.
