In vivo gene delivery by electroporation.

The physical phenomenon of electroporation has been successfully exploited in vitro for the delivery of genes, drugs, and other molecules with increasing frequency over the past two decades. This type of electrically mediated delivery has been translated into an in vivo setting in more recent years with a focus on therapeutic molecules. One promising area is the delivery of genes as a therapy.Advances in molecular medicine have produced a very large amount of information about genes that translate to therapeutic molecules when expressed in living cells. Current standard methods for transferring genes utilize viruses to deliver DNA into cells. These viral methods have not yielded optimal results in most cases. Therefore, there is an increasing interest in nonviral methods for gene delivery. In vivo electrically mediated gene delivery is an attractive alternative because of the site specific nature of delivery as well as the universal applicability of electroporation. A review of the studies performed to investigate and develop this new gene delivery technology is presented.
