PS species profiles in hBMSCs cultured for 9 days in the control (Ctrl) medium or medium supplemented with 18:2n-6 or 20:4n-6 (mole percent per total PS, mean ± SD). For the isobaric species (marked horizontally) having more than one quantitatively important species (acyl chain combination marked vertically), the two most important were listed (in the reading order the first one being the main species). Quantitatively important PI species are shown in the insert. When the double bond positions of the acyl chains were not marked, several isomers (revealed by GC-MS of fatty acids) were present in the cells for that particular chain. Statistics are as in Fig. 1.
