BACKGROUND Although polycations are among the most efficient nonviral vectors for gene transfer, the gene expression they allow is still too low for in vivo applications. To engineer more potent polycationic vectors, the factors governing the intracellular trafficking of a plasmid complexed with current polycations need to be identified. METHODS AND(More)
To identify the intracellular barriers to efficient gene transfer, we studied the intracellular trafficking of biotinylated plasmid DNA complexed with either fluorescein-conjugated lactosylated or mannosylated polylysine by confocal microscopy. Both are known to be taken up by cystic fibrosis airway epithelial cells (SigmaCFTE29o- cells), but their gene(More)
