Extended and stable gene expression via nucleofection of MIDGE construct into adult human marrow mesenchymal stromal cells

Human mesenchymal stromal cell (hMSC) is a potential target for cell and gene therapy-based approaches against a variety of different diseases. Whilst cationic lipofection has been widely experimented, the Nucleofector technology is a relatively new non-viral transfection method designed for primary...
