ABSTRACT
BACKGROUND: The orphan nuclear receptors Rev-erbα and Rorα play important roles in lipid metabolism and glucose metabolism. But it is unclear whether they are involved in bone metabolism. OBJECTIVE: To observe the expression of Rev-erbα and Rorα during the osteoblastogenesis process of bone marrow mesenchymal stem cells (BMSCs). METHODS: BMSCs were isolated and purified from C57BL/6 mice by the whole bone marrow adherence method followed by morphology observations and then BMSCs were induced to differentiate into osteoblasts and adipocytes. We detected their differentiation abilities using oil red O staining and alizarin red staining, respectively. Real-time PCR and western blot assay were conducted to detect the mRNA and protein levels of Rev-erbα and Rorα in BMSCs cultured in the osteogenic medium for 0, 7, 14 days. RESULTS AND CONCLUSION: BMSCs from C57BL/6 mice were mainly spindle-shaped and exhibited the swirl-like pattern of growth. Following induction, oil red O staining and alizarin red staining produced a positive reaction in these cells. Rev-erbα expression at both gene and protein levels decreased at 0, 7, 14 days after osteogenic induction, while Rorα expression increased at both gene and protein levels. These findings indicate that Rev-erbα and Rorα may participate in the osteoblastogenesis of BMSCs.
