    [摘要] 目的 探讨白藜芦醇对C3H10T1/2细胞成骨分化的作用及CXCL12、EGFR和CCL2基因表达的影响。 方法 采用CCK-8法检测不同浓度白藜芦醇对C3H10T1/2细胞增殖影响，碱性磷酸酶染色鉴定早期成骨分化，实时荧光定量PCR法检测CXCL12、EGFR和CCL2基因的表达。 结果 白藜芦醇在20 μmol/L浓度对C3H10T1/2细胞增殖没有影响(P > 0.05)，随着浓度增加，40、80、100 μmol/L的白藜芦醇明显抑制细胞增殖(P 0.05)。 结论 白藜芦醇能促进rhBMP-2诱导成骨分化。促成骨分化作用可能不是通过调控CXCL12、EGFR和CCL2基因的表达来实现。

    [Abstract] Objective To study the effects of resveratrol on early osteoblast differentiation and mRNA expression of CXCL12， EGFR and CCL2 of C3H10T1/2 mesenchymal stem cells. Methods The C3H10T1/2 cell proliferation was detected using CCK-8 after different concentrations of resveratrol. The early osteoblast differentiation was identified by alkaline phosphatase (ALP) staining. The mRNA expression of CXCL12 ......
