| Outline of Final Research Achievements |
A matrix-assisted laser desorption ionization (MALDI)-based mass spectrometer provides clear two-dimensional molecular identification with highly sensitive mass spectrometry from mixtures of ions generated on tissue surfaces. We applied this technology to the molecular identification of phospholipids in the human term placenta and found that placental some of pathological findings were associated with the distribution pattern of sphingomyelin (d18:1/16:0) and phosphatidylcholine (16:0/20:4) in stem and terminal villi. The findings suggested that these biopolymers may be involved in the maintenance and/or pathological changes placental villus structures.
