Executive Industry Relevance

This method addresses a critical bottleneck in gene therapy: achieving stable transgene integration in primary human cells resistant to conventional transfection. By combining a transcriptionally regulated hyperactive Sleeping Beauty transposase with integration-defective lentiviral delivery, it enables tunable, efficient genomic modification in therapeutically relevant cell types. The approach supports preclinical de-risking by providing a reproducible platform for functional validation before clinical translation.
