Polymeric micelle, the self-assembly of block copolymers with core-shell architecture, is a promising nanocarrier for drug and gene delivery. There are several relevant properties in polymeric micelle as nanocarrier systems, such as longevity in blood circula-tion, tissue-penetrating ability, spatial and temporal controlled drug release, and reduced inherent toxicity of cytotoxic reagents. | Workshops Abstracts WORKSHOPS WS 1 Nanotherapeutics WS1-1 Nanotherapeutics through polymer chemistry supra-molecular nanocarriers for gene and drug delivery K. Kataoka The University of Tokyo Materials Engineering Tokyo JAPAN Polymeric micelle the self-assembly of block copolymers with core-shell architecture is a promising nanocarrier for drug and gene delivery. There are several relevant properties in polymeric micelle as nanocarrier systems such as longevity in blood circulation tissue-penetrating ability spatial and temporal controlled drug release and reduced inherent toxicity of cytotoxic reagents. Also engineering of the block copolymer structure allows the preparation of polymeric micelles with integrated smart functions such as targetability as well as stimuli-sensitivity. This presentation overviews the recent achievements as well as the future perspectives of polymeric micelles as smart nanocarriers for drug and nucleic acid delivery. Notable anti-tumor efficacy against hypovascular cancer including pancreatic cancer and diffused-type stomach cancer of the doxorubicin-incorporated polymeric micelles with pH-responding property was demonstrated to emphasize a promising utility of the nanocarrier-modulated chemotherapy for the treatment of intractable cancers. Gene-loaded polymeric micelles were applied as non-viral vectors in the fields of regenerative medicine particularly bone regeneration. Generation of new bone in experimental animals was successfully achieved by transducting genes encoding differentiation factors using polymeric micellar carriers. Gene therapy by polymeric micelles was also demonstrated for intractable cardiovascular disease pulmonary hypertension by intratracheal transfer of therapeutic gene. Further the supramolecular assemblies including polymeric micelles polymer vesicles and photosensitive dendrimer assemblies were utilized as nanodevices directing to the new medical paradigm of smart nanotheranostic systems controlled by .
