After partial hepatectomy (PH), regenerating liver accumulates unknown lipid species. Here, we analyzed lipids in murine liver and adipose tissues following PH by thin-layer chromatography (TLC), imaging mass spectrometry (IMS), and real-time RT-PCR. In liver, IMS revealed that a single TLC band comprised major 19 TG species. Similarly, IMS showed a single phospholipid TLC band to be major 13 species. In adipose tissues, PH induced changes to expression of genes regulating lipid metabolism. Finally, IMS of phosphatidylcholine species demonstrated distribution gradients in lobules that resembled hepatic zonation. IMS is thus a novel and power tool for analyzing lipid species with high resolution.
