T3 (Triiodothyronine)

Triiodothyronine is one ingredient supplemented in the medium for inducing brown adipocytes differentiation.^[1]

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, 1 μM dexamethasone, 0.5 mM IBMX, 1 μM Rosiglitazone, and 2 nM 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 triiodothyronine). 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.
