Improved knowledge of all aspects of adipose biology will be required to counter the burgeoning epidemic of obesity. Interest in adipogenesis has increased markedly over the past few years with emphasis on the intersection between extracellular signals and the transcriptional cascade that regulates adipocyte differentiation. Many different events contribute to the commitment of a mesenchymal stem cell to the adipocyte lineage including the coordination of a complex network of transcription factors, cofactors and signalling intermediates from numerous pathways.

Adipocyte differentiation from the inside out.

We studied the effects of a thiazolidinedione (T-174) and retinoids on adipocyte differentiation in beef cattle. Stromal-vascular (SV) cells containing preadipocytes were prepared from perirenal adipose tissue of 21-mo-old Japanese Black steers. After confluence, these cells were cultured in 25 microM T-174, which is a specific ligand for an adipogenesis stimulating nuclear receptor (i.e., gamma subtype of peroxisome proliferator-activated receptor [PPARgamma]), with 1 microM all-trans retinoic acid (RA) or .4 to 40 microg/100 mL of retinol for 10 to 14 d. The number of cells accumulating lipid droplets was counted as morphologically differentiated adipocytes, and the activity of glycerol-3-phosphate dehydrogenase (GPDH), a biochemical index for the differentiation, was determined. The number of lipid-laden cells and GPDH activity were increased by the addition of T-174. All-trans retinoic acid completely blocked the stimulative action of T-174. The addition of retinol also decreased the number of lipid-laden cells and GPDH activity in a dose-dependent manner. These results showed that the thiazolidinedione stimulated adipocyte differentiation and the retinoids blocked the adipogenesis induced by the thiazolidinedione in primary culture of bovine SV cells. Peroxisome proliferator-activated receptor gamma may play an important role in adipocyte differentiation, and retinoids may interfere with the action of PPARgamma in cattle.

There are two types of brown adipocytes: classical brown adipocytes that form the brown fat depots and beige adipocytes that emerge in the white fat depots. Beige adipocytes have a low level of uncoupling protein 1 (Ucp1) expression in the basal state, but Ucp1 expression is increased in response to β adrenergic receptor activation. The present study explored the factors responsible for the differentiation of 3T3-L1 white preadipocytes to beige adipocytes. Significant expression of Ucp1 was not detected under any tested conditions in the absence of isoproterenol (Iso), an agonist of β adrenergic receptor. Iso-induced Ucp1 expression was significantly higher in the cells treated with a mixture of triiodothyronine (T3) and 3-isobutyl-1-methylxanthine (IBMX) for days 0–8 than in the control cells. Chronic IBMX treatment was indispensable for the enhanced Iso-induced Ucp1 expression, and treatment with additional rosiglitazone (Rosi) for days 0–8 further increased the Ucp1 expression. Recently, genes were identified that are predominantly expressed in beige adipocytes, which were induced from stromal vascular cells in white fat depots. However, the expression levels of the beige adipocyte-selective genes in the adipocytes induced by the mixture of T3, IBMX and Rosi did not differ from those in the control adipocytes. The present study indicates that 3T3-L1 cells can differentiate to beige-like adipocytes by prolonged treatment with the mixture of T3, IBMX and Rosi and that the gene expression profile of the adipocytes is distinct from those previously induced from white fat depots.
