Abstract

The cellular uptake and distribution of cationic liposomes Dc-Chol/DOPECFTR gene complexes were assessed by electronic and confocal laser scanner microscopy (CLSM) for the CFTR gene transfer to human adenocarcinoma and tracheal epithelial cell lines. Cationic lipid forms unilamellar and multilamellar vesicles capable of rapid and efficient transport of gene into target cells. The number of fluorescent complexes was increasing with time in cells up to 6 hours showing a punctate and homogeneous DNA distribution in the cytoplasmatic and nuclear compartments, including the nucleolus. No significant difference in the biochemical and cellular behavior was observed between the investigated system and other systems previously tested. This study adds new insights into the CFTR cationic liposome-mediated gene delivery.
