Abstract (original English)
The accumulation of fat, which results in obesity, is related to many metabolic disorders. Besides white and brown adipose tissue, beige adipose tissue has recently been recognized as a new type of accumulated fat. Mesenchymal stem cells (MSCs) have been shown to differentiate into brown adipocytes. Through analyzing levels of mRNA and protein markers associated with beige adipocyte, we found concomitant beige adipocyte differentiation upon induction of MSCs into brown adipocytes in a defined medium containing triiodothyronine, insulin, dexamethasone, and indomethacin. Moreover, we found that protein kinase A (PKA) modulators regulated MSC differentiation into brown or beige adipocytes. Activation of PKA by isobutylmethylxanthine or forskolin increased brown adipocyte differentiation and reduced beige adipocyte differentiation, while inactivation of PKA by KT-5720 or SC-3010 or the knockdown of PKA downstream cAMP response element-binding protein (CREB) decreased brown adipocyte differentiation and increased beige adipocyte differentiation. We also showed that increased brown adipocyte differentiation was accompanied by an increase in mitochondrial mass. In conclusion, we propose a model of beige/brown co-differentiation in MSCs and develop a method for controlling this differentiation via PKA modulation.
