제목 Hybrid hyaluronic acid/calcium phosphate gene delivery system enhanced transfection of human stem cells
초록 Human mesenchymal stem cells (hMSCs) have shown enormous potential in regenerative medicine and tissue engineering. However, current use of hMSCs in clinics is still limited since there is no appropriate way to control their behaviors in vivo such as differentiation to a desired cell type. Genetic modification of hMSCs may provide an opportunity of controlling behaviors of the cells in an active manner. One of the major huddles for genetic manipulation of hMSCs would be lack of efficient and safe gene delivery system. Herein, an organic-inorganic hybrid gene delivery system based on calcium phosphate (CAP) nanoparticles stabilized with catechol-derivatized hyaluronic acid (dopa-HA) conjugate. The dopa-HA/CAP nanoparticles showed significantly higher transfection in hMSCs than PEI 25kDa. In addition, delivery of BMP2 plasmid DNA with the dopa-HA/CAP formulation achieved desired level of osteogenic differentiation of hMSCs.
