Introduction: The advance in nucleic acids therapeutic had been outstanding in recent years, which have opened new possibilities in regenerative medicine to tackle many serious diseases. To make nucleic acids based therapy a reality, the fundamental problem of tissue specific cellular delivery has to be accomplished. Here we present a new approach to develop the next generation of delivery vectors.
Materials and methods: Hyaluronic acid were modified to complex DNA plasmids for luciferase transfection. Transfection: HCT 116 cells and mice where tranfected by adding HA-DNA complex. The transfection experiment with commercially available reagent polyethyleneimine (PEI) and plasmid alone were used as controls.
Results and discussion: Efficient tranfection was shown using the new non toxic and safe non viral vector. Using ECM components (such as hyaluronic acid or HA) that allow both in vitroandin vivo transfection of plasmid DNA in CD44 positive cells. The chemically modified ECM components (non-toxic) binds to nucleic acids and are taken in by cells by natural receptor mediated endocytosis. The amount transported via these routes naturally is around 10 gram per day to give a potential capacity far exceeding the need for transfection if it is targeted. By molecular association strategies (joining the bandwagon) it is now possible for nucleic acids to follow these pathways that utilise the highly efficient receptor mediated endocytosis- door opener into cells.
