Fig. 3: Untargeted lipidomics of marmoset brain sections.

a Scatter plot of lipid molecules detected in marmoset brain section. b Number of lipids detected at the structural depth of fatty acyl compositions or C=C positions. c Hierarchical clustering analysis using the correlation coefficient between lipid subclasses. A total of 40 samples were used for the correlation analysis without discriminating between different regions and ages to characterize lipid subclasses. Correlation analyses were performed using Pearson correlation coefficient. The p values obtained from these analyses were adjusted for multiple comparisons using the false discovery rate method. Adjusted p-values were classified into significance levels and displayed using symbols: *** for pā<ā0.001, ** for pā<ā0.01, and * for pā<ā0.05. d Total amounts of representative lipid subclasses in each region and age. Five regions including frontal lobe (FL), hippocampus (HC), midbrain (MB), cerebellum (CB), and medulla (MD) were analyzed. Error bars indicate the standard deviations of the four biological replicates in each group.
