Gene therapy for tissue repair: approaches and prospects.
Recent advances in molecular biology have resulted in the development of new technologies for the introduction and expression of genes in human somatic cells. This emerging field, known as gene therapy, is broadly defined as the transfer of genetic material to cells/tissues in order to achieve a therapeutic effect for inherited as well as acquired diseases. We and others are exploring the potential application of this technology to tissue repair. One primary focus has been to transfer genes encoding wound healing growth factors, a broad class of proteins which control local events in tissues such as cell proliferation, cell migration and the formation of extracellular matrix. Using several different strategies for gene transfer, wound healing growth factor genes have been introduced and expressed in cells and tissues in vitro as well as in vivo. Various experimental models of wound healing and tissue repair have been used to evaluate the efficacy of this new and exciting approach to tissue repair.
