Gene-based therapies for the induction of spinal fusion.
Numerous mesenchymal growth factors with osteogenic properties have now been identified. Although many of these proteins can induce bone formation when delivered on a carrier matrix, these approaches have not been fully developed in the laboratory or clinic. The expression of osteogenic proteins via direct or ex vivo gene therapy techniques is also compelling because high-level, long-term gene expression can now be achieved using novel viral and nonviral vectors. In this brief review the authors will highlight recent advances in genetic therapies for the induction of osteogenesis, as well as their potential use for the promotion of spinal arthrodesis.
