ESI-MS analysis of PC molecular species in BMMCs and CTMC-like cells. IL-3-maintained BMMCs (gray bars) and CTMC-like differentiated cells after coculture for 4 days with Swiss 3T3 cells in the presence of SCF (filled bars) from Pla2g4a+/+ and Pla2g4a−/− mice (A and B) or from Pla2g6+/+ and Pla2g6−/− mice (C and D) were subjected to ESI-MS analyses for PC molecular species on a positive ion mode. PC species bearing sn-2 fatty acids with a high degree (4) of unsaturation (A and C) and those bearing sn-2 fatty acids with no or a low degree (2) of unsaturation (B and D) were quantified. Values indicate the percentages of individual PC species relative to total PC mass (mean ± S.D., n = 3–4; *, p < 0.05).
