Figure 8
HB treatment enhanced TGF-β1 expression, decreased MMP9 production, and facilitated collagen growth. (a) immunofluorescence staining of TGF-β1 (red) and its quantitative results ( animals per group); scale bar: 200 μm, nucleus (blue); (b) MMP9 level (); (c) New collagen growth observed by using two-photon microscope at days 6 and 13 after wound surgery. The green indicated the background, and the purple indicated the new collagen tissue at the front of the wound healing. The data were expressed as , and significance was expressed as # vs Con and vs STZ.
