摘要 目的观察Runx-2转染的骨髓间充质干细胞复合纳米羟基磷灰石修补兔桡骨骨缺损的效果。方法将Runx-2骨髓间充质干细胞与纳米羟基磷灰石共培养设置为实验组(A组),设置e GFP-骨髓间充质干细胞组(B组),骨髓间充质干细胞组(C组)及空白组(D组)。建立兔桡骨骨缺损模型,并分别填入填充材料(D组不填充)。术后4、8及12周分别行X线检查,术后12周获取实验兔桡骨标本并行病理切片检查。结果 Runx-2骨髓间充质干细胞高表达Runx-2基因;术后实验组兔桡骨标本在外观、X线片及病理切片下均显示更好的骨性愈合。结论Runx-2骨髓间充质干细胞纳米羟基磷灰石能够很好修复兔桡骨缺损,证实其具有良好的骨缺损修复能力,可以作为人体骨缺损修复的生物复合材料。
