The aim of the present study was to evaluate the efficacy of novel nonviral gene delivery systems in cells of musculoskeletal origin. Primary cultures of lapine skeletal muscle cells, lapine articular chondrocytes, human cells from fibrous dysplasia and cell lines established from human osteosarcoma (SAOS-2), chondrosarcoma (CS-1), murine skeletal myoblasts (L8) and fibroblasts (NIH 3T3) were t...

Background: Low uptake of exogenous DNA by sperm and reduced number of fertilized oocyte by transfected sperm are the major obstacles for progression of sperm mediated gene transfer. Therefore, the modification of sperm mediated gene transfer procedure needs to be required. The purpose of this study was to evaluate the efficiency of FuGene 6 compare to lipofection in transfection medium for int...

The objective of this study was to establish conditions for transfection of a foreign gene into somatic cells using cationic lipid reagents and to evaluate the effects of transfection on in vitro development of somatic cell nuclear transfer (SCNT) embryos. Green fluorescent protein (GFP) gene was used as a foreign gene and a non-transfected somatic cell was utilized as a control karyoplast. Mon...

One of the most significant steps in gene expression studies is transferring genes into cell cultures. Despite there are different methods for gene delivery such as viral and non-viral producers, some cationic lipid reagents have recently developed to transfect into mam- malian cell lines. The main aim of this study was optimizing and improving lipocomplex based transient transfection procedure...

Transfection protocols and the reagents used to deliver nucleic acids into cells can affect cell physiology, leading to misinterpretation of results. Using microarray analysis and cell viability assays, we evaluated different transfection reagents to determine their effects on gene expression profiles. Results show that FuGENE 6 Transfection Reagent exhibits very low cytotoxicity, delivers high...

Commercially available lipid-based transfection reagents are widely used to deliver DNA to cells. However, these lipid-based transfection reagents show poor gene transfer efficiency in primary cells. Here, we demonstrate a simple method to improve gene transfer efficiency in primary fibroblasts and hepatoblasts using a combination of lipid-based transfection reagents. Our data show that combine...

Inducible NO synthase (iNOS) is overexpressed in inflammatory bowel diseases. An antisense oligonucleotide with good hybridization properties for iNOS mRNA was selected using RT-PCR. The oligonucleotide was reliably labeled with fluorine-18 using N-(4-[(18)F]fluorobenzyl)-2-bromoacetamide. Cellular uptake and efflux of oligonucleotide complexed with FuGENE-6 were rapid, unlike naked oligonucleo...

Target gene delivery is needed to induce cellular differentiation or a specific therapeutic effect. Electroporation is a relatively safe and simple technique to deliver nucleic acids to the cell that acts by rendering cells transiently permeable using short periods of high voltage. In stem cell research, human dental pulp stem cells (hDPSCS) are highly accessible, and they exhibit broad differe...

Metastatic breast cancer requires systemic treatment. We have developed a systemic gene therapy approach for breast cancer, consisting of a nonviral gene delivery system (SN) and a proapoptotic gene, bik. The transfection efficiency of SN carrying a reporter gene was 5-10 times higher than the common nonviral agents Fugene-6 and Lipofectamine in the presence of serum. The SN-bik gene complex in...
