摘要
背景: 到目前为止,骨形态发生蛋白2 (BMP-2)非病毒基因治疗的显著骨诱导潜能还不能完全用于治疗。这主要是由于基因传递弱,表达峰短,限制了治疗效果。 目的: 我们的目的是测试小圆DNA的应用,允许延长表达潜力。与传统的质粒DNA相比,它具有显著的优势。由于缺少细菌序列和由此导致的体积减小,使得安全使用和提高组织再生性能成为可能。 结果: 与转染传统BMP-2晚期质粒的细胞相比,转染BMP-2晚期小圆细胞的C2C12细胞骨钙素、碱性磷酸酶(ALP)活性和BMP-2蛋白含量均显著提高。此外,当质粒被引入人骨髓干细胞(BMSCs)时,显示出明显较高的碱性磷酸酶活性和矿化水平,显示出对干细胞方法的适应性。 结论:我们设计了一种具有高生物活性的BMP-2小圆质粒,有潜力满足骨再生领域非病毒基因治疗的临床需要。
