A Combination Cell and Gene Therapy Repairs Severe Bone Fractures

The progress in various approaches to gene therapy over the past decade has succeeded in reducing cost and increasing reliability. This has reached the point at which researchers can afford, from the point of view of both time and funding, to begin to combine gene therapies with other areas of medicine under development. In particular, reliable gene therapies targeting the controlling switches and dials of cell growth and regeneration should be a way to greatly improve the effectiveness of cell therapies and other, similar forms of regenerative medicine. The research reported below is a good example of the type, in which scientists combine a scaffold-based cell therapy with gene therapy to encourage local cells towards increased, controlled bone regrowth to replace severe fracture damage. There are many methods of delivery for the introduction of therapeutic genes. The familiar use of viruses as a vector for the transfection of genes into a cell is just one class of approach - perhaps the most obvious one, given that viruses are in essence machines whose primary purpose is to place DNA into cells. But there are other approaches. Considered in the larger context, this diversity is a good thing, as greater competition and exploration always leads to a superior end result once all is said and done. The method used here is one of the pore-forming variations, in which one or another form of stimulus induces cells to open pores in the cell membrane and let in the DNA-bearing...
