Abstract

Objective: Angiogenesis, formation of new vessels from pre-existing vessels, is an essential part of wound healing. We aimed to compare amniotic membrane extract with deferoxamine in angiogenesis and to assess any synergistic effect. Method: We examined four groups of rats (five per group): control, deferoxamine, amniotic membrane extract, and deferocxamine and amniotic membrane extract in combination. A distal-based skin flap was created. Deferoxamine (100mg/kg), amniotic membrane extract (0.1mg/ml), and the combination of both were injected subcutaneously every other day in 10 separate points (0.1 ml at each point) in the skin flap. On day 11, the animals were euthanised for histopathological evaluation. Results: Results indicated that the amniotic membrane extract raised the angiogenic markers, particularly new vessel numbers (p<0.008) and CD31+ compared with controls (p < 0.003), and deferoxamine increased new vessel numbers and Von Willebrand factor (vWF) significantly compared with controls (p < 0.008). There was an increase in angiogenic factors in the combined group, however, this was not statistically significant difference was observed. There was no difference between amniotic membrane extract and deferoxamine. Conclusion: Amniotic membrane extract or deferoxamine could be used interchangeably in angiogenesis within wound healing due to their high safety and availability. © 2018 MA Healthcare.
