potential than adult stem cells for research and possible
therapy.
The Gene Therapy Advisory Committee (GTAC) is the
national research ethics committee for gene therapy clinical
research. GTAC’s definition of gene therapy is as follows: ‘The
deliberate introduction of genetic material into human
somatic cells for therapeutic, prophylactic or diagnostic purposes.’
This definition, and hence the remit of GTAC, encompasses
techniques for delivering synthetic or recombinant
nucleic acids into humans:
• genetically modified biological vectors, such as viruses or
plasmids;
• genetically modified stem cells;
• oncolytic viruses;
• nucleic acids associated with delivery vehicles;
• naked nucleic acids;
• antisense techniques (for example, gene silencing, gene
correction or gene modification);
• genetic vaccines;
• DNA or RNA technologies, such as RNA interference;
• xenotransplantation of animal cells, but not solid organs.
