Outline of Final Research Achievements |
Using matrix-assisted laser desorption/ionization imaging mass spectrometry and time-of-flight secondary ion mass spectrometry, we succeeded in single-cell imaging mass spectrometry of lipid by optimizing slide preparation for FACS-isolated blood cells and sample fixation. By single-cell imaging mass spectrometry we revealed different lipid composition in lymphocyte subsets and lipid metabolic change in breast cancer cell line, breast cancer stem cells and multiple myeloma (MM) cells. In addition we showed that palmitic acid, which was deceased in MM cells, is a potential multiple myeloma-specific drug.
