Changes of phospholipids detected by LC-MS/MS during differentiation of iPSC to ECpa. Levels of pPE (a), pPC (b), and SM (c) during differentiation of iPSC to ECpa were examined. PE (34:0), PC (30:0), and SM (35:0) were used as internal standards, with 1 μg being added to 100 μg of protein solution. (*p < 0.05 compared with iPSC).
