By linking transgene expression with that of a housekeeping gene, SLEEK (selection by essential-gene exon knock-in) enables efficient knock-in of complex cargos in a variety of clinically relevant cell types. Using SLEEK, we were able to substantially improve the tumor suppression ability and in vivo persistence of a cell therapy.
