| Summary: | <p>Abstract</p> <p>Background</p> <p>fatty acids are considered to be effective components to promote wound healing and <it>Lucilia sericata </it>larvae are applied clinically to treat intractable wounds. We aimed to investigat the effect of fatty acid extracts from dried <it>Lucilia sericata </it>larvae on murine cutaneuous wound healing as well as angiogenesis.</p> <p>Results</p> <p>On day 7 and 10 after murine acute excision wounds creation, the percent wound contraction of fatty acid extracts group was higher than that of vaseline group. On day 3, 7 and 10 after wounds creation, the wound healing quality of fatty acid extracts group was better than that of vaseline group on terms of granulation formation and collagen organization. On day 3 after wounds creation, the micro vessel density and vascular endothelial growth factor expression of fatty acid extracts group were higher than that of vaseline group. Component analysis of the fatty acid extracts by gas chromatography-mass spectrometry showed there were 10 kinds of fatty acids in total and the ratio of saturated fatty acid, monounsaturated fatty acid and polyunsaturated fatty acid (PUFA) was: 20.57%:60.32%:19.11%.</p> <p>Conclusions</p> <p>Fatty acid extracts from dried Lucilia sericata larvae, four fifths of which are unsaturated fatty acids, can promote murine cutaneous wound healing probably resulting from the powerful angiogenic activity of the extracts.</p>
