Summary of the fold changes of lipid classes in GrEVs relative to those in GrEXs. The fold change values are shown as the means ± standard deviations (n = 9 per group; three biological replicates, each with three technical replicates). Statistical significance was analyzed by Student’s t-tests for two groups.
