Abstract
Background/objective
Fetal wound repair seems a relatively efficient process when compared to wound repair during adulthood, which may be explained by the effects of the fetal environment. This study examined the effects of an amnion cell culture medium (ACCM) on skin wound healing in a rat experimental model.
Methods
Sixteen adult female Wistar albino rats were used in this experimental animal study (treatment group, n = 8; control group, n = 8). Surgical wounds were formed on the dorsal skin of each rat. A commercially available ACCM was administered daily over each of the wound in the treatment group for 14 days and the control group did not receive any treatment. Wounds were evaluated for tissue perfusion with laser doppler, tissue superoxide dismutase (SOD), glutathione peroxidase (GPX), and malondialdehyde (MDA) levels as well as histopathological examination.
Results
Controls had significantly higher tissue SOD levels when compared to the treatment group (10.0 ± 3.2 vs 6.7 ± 1.2, P = .005); however, the 2 groups did not differ in terms of tissue GPX and MDA levels. For open wounds, inflammation and neovascularization were more prominent in the ACCM group at day 14. However, at day 21 neovascularization and granulation were more prominent in controls. For closed wounds, neovascularization was more prominent in controls at days 14 and 21. The 2 groups did not differ in terms of tissue perfusion.
Conclusion
Although marginal difference was found between controls and ACCM group for several parameters, findings of this study do not support beneficial effect of ACCM on wound healing.
