重组质粒pIRESneo-EGFP-BDNF构建及转染骨髓间充质干细胞
Medical Research and Education(2012)
Abstract
目的探讨重组质粒pIRESneo-EGFP-BDNF构建及转染至骨髓间充质干细胞(MSCs)制备BDNF基因工程细胞的方法。方法将pEGFP(N1)-BDNF质粒进行改造与pIRESneo相连结,构建携带BDNF的高拷贝质粒pIRESneo-EGFP-BDNF,采用电转染技术转染骨髓MSCs,经G418筛选,通过倒置荧光显微镜判断转染效率,采用Western blot方式判定转染细胞是否表达BDNF蛋白。结果经过双酶切鉴定,pIRESneo-EGFP-BDNF携带EGFP及BDNF基因,以EGFP为报告基因,质粒构建成功;通过电穿孔技术以及G418筛选,提高pIRESneo-EGFP-BDNF转染骨髓MSCs效率。结论成功制备高效表达携带BDNF基因的质粒,且转染骨髓MSCs,为进一步开展BDNF基因治疗神经系统变性疾病奠定基础。
