目的

本研究旨在探讨BMP-2/Smads信号通路对骨代谢失衡大鼠骨髓间充质干细胞（rBMSCs）成骨分化的影响。

方法

切除雌性SD大鼠双侧卵巢，建立大鼠骨代谢失衡模型，即骨质疏松（osteoporosis，OP）模型。通过成骨诱导鉴定rBMSCs的成骨分化。采用脂肪诱导和流式细胞术（FCM）检测脂肪分化和rBMSC表面标志物的表达。将rBMSCs分为空白组、NC组（转染大鼠rBMSCs的阴性对照质粒）、SI-BMP2组（转染大鼠rBMSCs具有低表达BMP-2质粒）和OE-BMP2组（转染大鼠rBMSCs具有高表达BMP-2质粒）。Western blot和定量实时聚合酶链反应（qRT-PCR）检测关键因子和成骨相关因子的表达水平。茜素红染色观察钙化结节的形成。碱性磷酸酶染色测定ALP活性。

结果

OP组大鼠体重增加，骨密度下降（均P<0.01）。OP大鼠rBMSCs具有成骨分化和成脂分化能力，CD44（91.3±2.9%）和CD105（94.8±2.1%）高表达。与空白组相比，OE-BMP2组BMP-2和SMAD1水平升高，钙化结节和ALP阳性染色面积增加（均P<0.05）。OE-BMP2组RUNX2、OC、OPN表达水平均高于空白组（均P<0.05）。SI-BMP2组的结果与OE-BMP2组相反。

结论

BMP-2激活的BMP信号通路可促进骨代谢失衡大鼠rBMSCs的成骨分化。

Objective

The purpose of this study was to investigate the effect of BMP-2/Smads signaling pathway on osteogenic differentiation of bone marrow mesenchymal stem cells (rBMSCs) in rat with bone metabolism imbalance.

Methods

Ovaries of female SD rats were excised and OP model was established. The osteogenic differentiation of rBMSCs was identified by osteogenic induction. Fat induction and flow cytometry (FCM) were used to detect fat differentiation and the expression of rBMSC surface markers. rBMSCs were divided into blank group, negative control (NC) group (transfected with NC BMP-2 plasmid), SI-BMP2 group (transfected with low expressing BMP-2 plasmid) and OE-BMP2 group (transfected with high expressing BMP-2 plasmid). Western blot and quantitative real-time PCR were used to detect the expression of key factors and osteogenic related factors. The formation of calcified nodules was observed by alizarin red staining. ALP activity was determined by alkaline phosphatase staining.

Results

In OP group, the weight and bone mineral density of rats increased (P<0.01). rBMSCs of OP rats have the ability of osteogenic differentiation and lipogenic differentiation. CD44 (91.3±2.9%) and CD105 (94.8±2.1%) are highly expressed. Compared with the blank group, the level of BMP-2 and Smad1 in OE-BMP2 group increased, and the area of calcified nodule and ALP positive staining increased (P<0.05). The expression level of Runx2, OC and OPN in OE-BMP2 group was higher than that in blank group (P<0.05). The results of SI-BMP2 group were opposite to those of OE-BMP2 group.

Conclusion

The BMP signaling pathway activated by BMP-2 can promote the osteogenic differentiation of rBMSCs in OP rats.
