Liothyronine (Triiodothyronine, T3)

La T3 (Triiodothyronine) est un ingrédient ajouté au milieu pour induire la différenciation des adipocytes bruns.[1]

• Lignées cellulaires

  Brown preadipocytes

• Concentrations

  2 nM

• Temps dincubation

  2 days

• Méthode

  Brown preadipocytes were isolated from perirenal adipose tissues of Chuanzhong black goats (1 day after birth). The cells were cultured in DMEM/F12 containing 10% fetal bovine serum and 2% penicillin/streptomycin and placed in an incubator (5% CO₂, 37°C). Until 100% confluence, DMEM/F12 was supplemented with 2% FBS containing 5 μg/ml of insulin, 0.5 mM IBMX, and 2 nM T3 (Triiodothyronine) to induce brown adipocytes differentiation. Two days later, the induced medium was changed to a maintenance medium (DMEM/F12 supplemented with 2% FBS, 5 μg/ml of insulin, and 2 nM of this compound). Cells were harvested 8 days after differentiation. L-carnitine was added to the medium throughout the differentiation process and supplemented at 600 μΜ. SiAMPKα (GAAGAGAAATTCAGAACCT)15 were transfected by Lipofectamine 3000. Lipid droplets were stained using Oil Red O solution. After staining, 1 ml isopropanol was used to dissolve the oil red O dye, and the absorbance at 510 nm was detected.
