A novel “chassis” PSC line for precise safe harbor site integration via selection-aided RMCE

Stem Cell Research
We describe here a human pluripotent stem cell line (hPSC) designed to serve as an acceptor (a “chassis” cell line) for the recombination-mediated cassette exchange (RMCE)-mediated precise insertion of DNA fragments into a safe harbor locus.

Computationally defined and in vitro validated putative genomic safe harbour loci for transgene expression in human cells

eLife
Selection of the target site is an inherent question for any project aiming for directed transgene integration. Genomic safe harbour (GSH) loci have been proposed as safe sites in the human genome for transgene integration.
