Gene therapists cannot track location, magnitude or duration of gene expression following somatic gene delivery. Consequently, they cannot correlate somatic gene transfer and phenotypic responses, since variations in gene delivery, gene expression levels and duration of gene expression cannot be monitored following gene administration. We developed two reporter genes whose expression can be non-invasively, quantitatively and repetitively monitored, in living individuals, by reporter protein-dependent sequestration of positron-labeled reporter probes, using positron emission tomography. We describe gene delivery systems from which therapeutic and PET reporter genes are co-expressed and demonstrated, using microPET in murine models, their ability to quantitate somatic gene transfer.
