Mean percentage of the fatty acid composition of exosome membranes extracted from HCEC-1CT and Caco-2 cell lines. All data represent the results of three different experiments (mean % ± SD). p-value has been determined by a paired Student t test. The bold font is represent the ration between arachidonic acid and eicosapentanoic acid for both cell lines, with standard deviation.
