We have researched gene transfection using hydrogen bonding polymer/DNA complex prepared by ultra high pressure technology. In this study, for effective gene transfection, we investigated the preparation of nano-hydroxyl apatite (HAp)/PVA/DNA complex including nano-scaled HAp particles promoting endosomal escape. Gene transfection was carried out using fluorescent labeled plasmid DNA molecules. After 1hour incubation, the effective cellular uptake of HAp/PVA/DNA complexes comparison with PVA/DNA complex and DNA was observed by fluorescent microscope, and then high transfection efficiency was achieved using HAp/PVA/DNA complexes. These results indicate the effective DNA release from endocytosis.
