Samples of dorsal skin from these animals were subjected to hematoxylin and eosin staining or Masson’s trichrome staining. In addition, immunohistochemical analyses and real-time polymerase chain reaction analyses were conducted to detect MMP-3 and MMP-9 expression.Results: After 1 week, both dermal thickness and collagen fiber density were significantly increased in the BMSC and combination treatment groups as compared to the control group (P< 0.05), while both of these parameters were significantly increased in all treatment groups after 4 weeks relative to the control group (P< 0.05), with the most pronounced effect in the combination therapy group (P< 0.05). MMP-3 and MMP-9 mRNA and protein levels in the treatment groups were decreased relative to the control group after 4 weeks.Conclusion: Combination BMSC and carbon dioxide laser therapy was more effective than either of these therapeutic approaches in isolation as a treatment for photoaged skin. The improvement of effect may be due to the decrease of MMP-3 and MMP-9 expression in combination therapy.Keywords: bone marrow mesenchymal stem cell, fractional carbon dioxide laser, photoaging, matrix metalloproteinase, mouse model |
