Ozone oil promoted the expression of fibroblast genes
(A) Real-time PCR results showing that ozone oil increases the fibroblast marker genes, collagen I, α-SMA, and TGF-β1 after injury in a time-dependent manner. (B,C) Western blotting results showthat the protein expression of these fibroblast genes is also increased after injury. Ozone oil further increases the expression of these genes. Error bars represent the mean ± S.D.; *P<0.05, **P<0.01, and ***P<0.01.
