Accelerates Skin Wound Healing by Regulating the Expression of MMPs and TGF-β.

is one of the medicinal plants used traditionally for treatment of wounds. We intended to investigate the wound healing effect of the powder of (UP) root bark in a mouse wound healing model. We also determined the mechanisms of effects of in skin and skin wound healing effects using a keratinocyte model. Animal experiments showed that the wound lesions in the mice decreased with 200 mesh root bark powder and were significantly reduced with treatment by UP, compared with those treated with (UM). Results from in vitro experiments also revealed that UP extract promoted the migration of human skin keratinocytes. UP powder treatment upregulated the expression of the matrix metalloproteinase-2 and -9 protein and significantly increased transforming growth factor (TGF)-β levels. We confirmed that topical administration of the bark powder exerted a significant effect on skin wound healing by upregulating the expression of MMP and transforming growth factor-β. Our study suggests that may be a potential candidate for skin wound healing including epidermal skin rejuvenation.
