In vitro non-viral gene delivery with nanofibrous scaffolds

In vitro non-viral gene delivery with nanofibrous scaffolds

Extracellular and intracellular barriers typically prevent non-viral gene vectors from having an effective transfection efficiency. Formulation of a gene delivery vehicle that can overcome the barriers is a key step for successful tissue regeneration. We have developed a novel core-shelled DNA nanoparticle by invoking solvent-induced condensation of plasmid DNA (beta-galactosidase or GFP) in a ...

Controllable delivery of non-viral DNA from porous scaffolds.

The inductive approach to tissue engineering combines three-dimensional porous scaffolds with drug delivery to direct the action of progenitor cells into a functional tissue. We present an approach to fabricate scaffolds capable of controlled, sustained delivery by the assembly and subsequent fusion of drug-loaded microspheres using a gas foaming/particulate leaching process. DNA-loaded microsp...

Non-Viral Delivery Systems in Gene Therapy

Recent advances in molecular biology combined with the culmination of the Human Ge‐ nome Project [1] have provided a genetic understanding of cellular processes and disease pathogenesis; numerous genes involved in disease and cellular processes have been identi‐ fied as targets for therapeutic approaches. In addition, the development of high-throughput screening techniques (e.g., cDNA microarra...

Nanofibrous scaffolds in biomedical applications

Nanofibrous scaffolds are artificial extracellular matrices which provide natural environment for tissue formation. In comparison to other forms of scaffolds, the nanofibrous scaffolds promote cell adhesion, proliferation and differentiation more efficiently due to having high surface to volume ratio. Although scaffolds for tissue engineering have been fabricated by various techniques but elect...
