From: Metabolomic profiling of exosomes reveals age-related changes in ovarian follicular fluid
Metabolomic analysis of exosomes derived from FF of the advanced age group and young group. A PCA scores of metabolite profiles between the advanced age group and young age group. B OPLS-DA model of metabolite profiles between the advanced age group and the young age group. C The proportion of identified and unknown metabolites and other components in the sample, as well as the categories and the proportion of identified metabolites in the sample, were also analysed separately. D Z score heatmap of an overview of metabolic profiles in all of the samples. The heatmap colour code indicates relative metabolite abundance: red indicates increased levels, and green indicates decreased levels in advanced age vs. young control
