Objective: This study investigated the effect of purified Carthamus tinctorius (C. tinctorius) extracted with a hot water and ethanol method on adipogenic differentiation of mouse bone marrow-derived mesenchymal stromal stem cells (mBMSCs).
Methods: The C. tinctorius was extracted using hot water and ethanol. The samples were concentrated by a rotary evaporator and were then dried using a freeze-dryer. The mBMSCs were cultured and maintained in a minimum essential medium eagle alpha (α-MEM) supplemented with 10% FBS and 1% antibiotic antimycotic solution. To induce adipogenic differentiation, the cells were treated with Dulbecco’s modified eagle’s medium-low glucose (DMEM-LG) containing 1 mg/mL insulin, 1 mM dexamethasone, and 0.5 mM 3-isobutyl-1-methylxanthine. To evaluate the adipogenic differentiation ability, oil-red O staining was performed after adipogenic differentiation for 21 days. The mRNA expression and protein level of adipogenic-related genes were quantified by quantitative real-time PCR and western blotting, respectively.
Results: In the results of the MTT assay, no concentrations of C. tinctorius extracts showed toxicity on mBMSCs, so we fixed the treatment concentration of the extract at 100 ng/mL. In oil-red O staining, the water-C. tinctorius extract treatment significantly decreased adipogenic differentiation compared with the control and ethanol extract groups. The water-C. tinctorius extract group in particular showed reduced mRNA and protein expression of Peroxisome proliferator-activated receptor gamma (Pparγ) and CCAAT/enhancer-binding protein alpha (C/ebpα), which are adipogenic-related transcription factors.
Conclusion: These data suggest that extract of C. tinctorius decreased the adipogenic differentiation of mBMSCs, while only water-C. tinctorius extract had an effect on different adipogenesis in mBMSCs. The C. tinctorius will be a useful therapeutic reagent for the prevention of obesity-related diseases such as diabetes, hyperlipidemia, coronary artery disease, and osteoporosis.
