Comparison of Sendai Virus-Mediated Gene Transfer Efficiency to Adhesive and Floating Adipose Tissue-Derived Stem Cells
Abstract:Sendai virus (SeV) vectors have potential clinical applications because they can efficiently introduce foreign genes without toxicity into various organs. A recent study reported the green fluorescent protein (GFP) gene transfer to adipose tissue-derived stem cells (ASCs) with SeV vectors results in more efficient expression of GFP than AdV and identified the preservation of the multilineage potential of ASCs transfected with SeV vectors. This study assessed the gene transfer efficiency to floating ASCs with SeV vectors. Although a slight cytotoxicity was observed, the efficiency of gene transfer to cells in the floating state was much higher at all times and all concentrations at MOIs of 2, 10, and 20 than in the adhesion state. Moreover, ASCs transfected with SeV vectors in floating state have the same potential for their differentiation into specific tissues, such as adipocytes and osteocytes, as untransfected ASCs. These data suggest that SeV transfection to ASCs in the floating state could therefore be useful for gene transfer technology.

More about this publication?
- Cell Transplantation publishes original, peer-reviewed research and review articles on the subject of cell transplantation and its application to human diseases. To ensure high-quality contributions from all areas of transplantation, separate section editors and editorial boards have been established. Articles deal with a wide range of topics including physiological, medical, preclinical, tissue engineering, and device-oriented aspects of transplantation of nervous system, endocrine, growth factor-secreting, bone marrow, epithelial, endothelial, and genetically engineered cells, among others. Basic clinical studies and immunological research papers are also featured. To provide complete coverage of this revolutionary field, Cell Transplantation will report on relevant technological advances, and ethical and regulatory considerations of cell transplants. Cell Transplantation is now an Open Access journal starting with volume 18 in 2009, and therefore there will be an inexpensive publication charge, which is dependent on the number of pages, in addition to the charge for color figures. This will allow work to be disseminated to a wider audience and also entitle the corresponding author to a free PDF, as well as prepublication of an unedited version of the manuscript.
