Liver sinusoidal endothelial cells as possible vehicles for gene therapy: a comparison between plasmid-based and lentiviral gene transfer techniques.
ENDOTHELIUM-JOURNAL OF ENDOTHELIAL CELL RESEARCH(2009)
摘要
Liver sinusoidal endothelial cells (LSECs) constitute an attractive target for gene therapy of several liver and systemic diseases. However, there are few reports showing an efficient plasmid-based or viral methodology to deliver recombinant genes into these cells. In the present study, the authors evaluated in vitro gene transfer efficiency of standard plasmid-based techniques (i.e., electroporation, lipofection, and calcium phosphate) and lentiviral-mediated gene transduction into primary murine LSECs, using reporter genes. The results show that electroporation is the most effective in vitro plasmid-gene transfer method to deliver GFP into LSECs (31%), as compared with lipofection and calcium phosphate transfection (6% and 4%, respectively). However, lentiviral transduction resulted in higher, efficient, and stable gene transfer (70%) as compared with plasmid-based techniques. Conclusions: The highly efficient gene expression obtained by lentiviral transduction and electroporation shows that these methodologies are highly reliable systems for gene transfer into LSECs.
