Figure 4. Downregulation of miR-27-3p promotes wound healing in vivo. (A) Digital photo of wounds treated with PBS, agomiR-27-3p, or antagomiR-27-3p. (B) Rate of wound-closure of the three groups. (C) Masson’s trichrome staining of wound sections treated with PBS, agomiR-27-3p, or antagomiR-27-3p. (D) Quantitative analysis of the mean intensity of Masson-stained areas in the three groups. (E) qRT-PCR evaluating the level of collagen 3, MMP1 and MMP3 expression. n=5. *p<0.05, **p<0.01, ***p<0.001.
