The development of safe and efficient gene delivery systems is the key to the overall success of gene therapy. This work introduced a MNP-based nonviral gene delivery approach for transfection in clinically relevant cells. Moreover, the in vitro mechanism studies could explained the beneficial properties of the proposed carrier design. This work demonstrated, that proposed system could efficiently and safely transfect human bone marrow derived mesenchymal stem cells. Additionaly, the clinical perspectives of MNP-based gene therapy were discussed and evaluated in this dissertation.<eng>
