摘要: 目的探讨重组NF1基因转染人增生性瘢痕成纤维细胞的可行性,以及转染NF1基因对细胞增殖速率和Ⅰ、Ⅲ型胶原合成的影响。方法体外重组NF1基因,借助真核表达载体系统,转入体外培养的人增生性瘢痕成纤维细胞,通过激光共聚焦显微镜观察报告基因表达,并确定细胞转染效率。应用Real time PCR法比较转染前后NF1 mRNA及Ⅰ、Ⅲ型胶原mRNA的表达;采用CCK-8比色法,比较转染细胞与未转染细胞增殖状况。结果基因转染后,约50%的被转染细胞表达绿色荧光;NF1 mRNA在转染组、转染空载体组、未转染组细胞中的表达分别为:7.27±1.16、2.01±0.38、1.87±0.29,转染组NF1 mRNA相对表达量较未转染组和转染空载体组明显增高(P<0.01,n=5);Ⅰ、Ⅲ型胶原mRNA在转染组、转染空载体组、未转染组细胞中的表达分别为:3.01±0.48和2.05±0.25、0.89±0.18和0.94±0.16、0.99±0.11和0.92±0.19;转染组Ⅰ、Ⅲ型胶原mRNA相对表达量较未转染组和转染空载体组均明显增高(P<0.01,n=5)。结论瘢痕成纤维细胞可作为NF1转染的靶细胞,NF1基因可能是导致...

Abstract: Objective To explore the feasibility of transfecting recombinant NF1 into hypertrophic scar fibroblasts and investigate the proliferation and collagen Ⅰ,Ⅲ synthesis of transfected cells. Methods Recombinant human NF1 gene was transfected into hypertrophic scar fibroblasts with the karyocyte expressive vector. The expression of NF1 gene, collagen Ⅰ, Ⅲ mRNA was quantified by real time PCR. The changes of cell proliferation were observed with CCK-8 colorimeter. Results Transfected hypertrophic scar fibroblasts...
