"Differentiation of Chub-S7 cells
Cells were grown in a mixture of DMEM/F12 media supplemented with 10% FBS, 2 mM glutamine, 100 U/ml penicillin/streptamycin until confluency. For differentiation, cells were cultured with a serum-free medium consisting of a mixture of DMEM/F12 media supplemented with 15 mM NaHCO3, 17 muM D-panthotenic acid, 15 mM Hepes, 33 muM biotin, 10 mug/ml transferrin, 1 nM triiodothyronin, 850 nM insulin and 500 mug/ml fetuin. This medium, referred to as 'basal medium', was supplemented with 1 muM Dex and 500 muM IBMX from day 0 to 3. Dex was maintained alone or with 1 muM BRL49653 from day 3 to 17 in order to promote differentiation. As stated in Results, OA complexed with bovine serum albumin (BSA; ratio OA-to-BSA: 5 : 1) was added to the medium containing BRL49653 from days 10 to 17. Lipid accumulation in differentiated cells was visualized by Oil-red O staining as previously described.13 All the experiments on Chub-S7 cell characterization were performed between passages 18 and 32 (69–122 PDs)."
