摘要(Abstract)：

[目的]比较青少年特发性脊柱侧凸(AIS)患者与正常人骨髓间充质干细胞的成脂分化过程中基因表达的差异。[方法]收集本院脊柱侧弯中心2011年12月~2012年12月收治的AIS患者20例的骨髓血,同时采集10例年龄段性别接近的志愿者骨髓血作为对照组。采用密度梯度离心法提取MSC细胞,培养至P3流式细胞仪定性。诱导成脂分化14 d后提取全RNA进行Affymetrix 3'IVT表达谱芯片检测。对主要检查结果进行RT-PCR验证,并且对结果中特异性高表达的Thrsp蛋白的表达情况进行Western blot检验。[结果]受试者骨髓血均成功采集分离,密度梯度离心分离MSCs并培养至P3,流式细胞仪验证其性质,成脂分化培养14 d后苏木红染色定性为脂肪细胞,提取全RNA电泳条带清晰,表达谱芯片检测结果显示AIS患者MSC在成脂分化过程中有111条基因表达上调,189条基因表达下调。Western blot检验结果显示Thrsp蛋白在脂肪细胞中高度表达。[结论]AIS来源MSCs成脂分化相关差异表达的300条基因可能参与了AIS的发生和发展,Thrsp基因可能是导致MSCs分化差异性的关键因素。
