Abstract:
OBJECTIVE:The fractional laser and topical retinoic acid treatment have been applied for skin rejuvenation; however, the possible molecular mechanism of promoting remodeling of dermis is not clearly. Here we aimed to compare the effects of 10600 nm CO2 fractional laser and topical retinoic acid formulation on the skin collagen proliferation of Wistar rats, and to further explore the possible molecular mechanism of promoting remodeling of dermis. MATERIALS AND METHODS:The hair on the back of Wistar rats was removed, and the back was divided equally into four regions with the cross-streaking method: A (the control group), B (the retinoic acid group), C (retinoic acid and fractional laser combination treatment group), and D (the fractional laser group). Specimens were collected at 3rd day and in 1-8 weeks after CO2 fractional laser irradiation; then they were used for detection of the changes of dermis thickness and content of hydroxyproline in the four regions of the rats' back. Real-time PCR method was used to detect the dynamic changes of the expression level of type III procollagen mRNA and the expression levels of miR-29a, Akt and transforming growth factor-β (TGF-β) mRNA at 3rd week in the skin tissue of Wistar rats. RESULTS:The thickness of dermis, content of hydroxyproline and expression level of type III procollagen mRNA in the treatment groups (B, C, and D) were found all significantly increased compared with those in the control group (A) (p<0.05); at 3rd week, up-regulation of Akt and TGF-β mRNA expression and down-regulation of miR-29a mRNA expression were observed in the treatment groups (B, C, and D). The difference in the combination treatment group (C) was the most significant (p<0.05). CONCLUSIONS:These results demonstrate that retinoic acid formulation and CO2 fractional laser both can promote collagen proliferation and reconstruction, with the skin rejuvenation efficacy in group C > group D > group B. miR-29a/Akt/TGF-β signal pathways may play a certain role in the promotion of collagen synthesis and proliferation.
