ObjectiveTo investigate the effects of migration and expression from chemokine receptor 4 (chemokine receptor-4, CXCR4) of rat bone marrow mesenchymal stem cells (BMSCs) which were pretreated by atorvastatin (ATV) in vitro.MethodsIsolated, cultivated, identified the BMSCs, pretreated P4-P6 of BMSCs with different concentrations of ATV for 12 hours. The experimental group was divided into control group, 0.1 nM/L (group 0.1 nM), 1 nM/L (1 nM group), 10 nM/L (10 nM group), 100 nM/L (100 nM group), 1 000 nM/L (1 000 nM group). The mRNA and protein of CXCR4 were determined by real time-polymerase chain reaction and Western blot. Immunofluoreseence assay were used to detect the expression levels of CXCR4. The migration ability of BMSCs were measured by transwell chamber.ResultsImmunofluoreseence assay showed the protein level of CXCR4 of group 1 nM and 10 nM were significantly higher than the other group. RT-PCR and Western blot showed the protein and mRNA level of CXCR4 in 10 nM was higher than that in group 1 nM. The migration ability of group 10 nM was higher than 1 nM and control group.ConclusionsATV can be dose-dependent promote expression levels of CXCR4 of BMSCs cultivated in vitro.
