Fig. 2.
Distribution of phosphatidylcholine (PC) molecular species in murine testes. Optical images of a testis of a mouse from the dietary administration group (a and b). Regions of matrix-assisted laser desorption ionization mass spectrometry imaging (MALDI-MSI) analysis are highlighted. Distributions of PC(36:5) and PC(36:4) (c–f). A merged image of PC(36:5) and PC(36:4) (g and m). Optical images of a testis of a mouse from the gavage group (i and j). Regions of MALDI-MSI analysis are highlighted. Distributions of PC(36:5) and PC(36:4) (k–n). A merged image of the distributions of PC(36:5) and PC(36:4) (o and p); n=5. Scale bars=500 µm (optical image) and 1000 µm (MALDI-MSI data).
