Fatty acid composition of lipid fractions in white- and brown-like adipocytes derived from human mesenchymal stem cells.

ABSTRACT: White and brown adipocytes differ markedly in lipid composition and metabolic function. White adipocytes primarily serve as energy storage depots, whereas brown adipocytes are mitochondria-rich and specialized for thermogenesis. However, the lipidomic profiles of white-like (WLAs) and brown-like adipocytes (BLAs) differentiated from human mesenchymal stem cells (MSCs) remain incompletely characterized. Human adipose-derived MSCs were differentiated into WLAs and BLAs. Lipid fractions were isolated and analysed by gas-liquid chromatography. Fatty acid composition data were used to calculate indices of stearoyl-CoA desaturase-1 (SCD1) activity, elongation, and ω6 synthesis. Compared to MSCs, BLAs showed consistently elevated oleate (≥4.2-fold) and stearate (≥2.3-fold), along with reduced pal
