Genome engineering and especially integration of large DNA payloads in human pluripotent stem cells (hPSC) remains challenging largely due to the sensitive nature of hPSCs. Site specific recombinases such as the serine integrase Bxb1 have been utilised successfully to target hPSC, however the targeting efficiencies remain low. Here we leveraged codon optimisation, inclusion of a nuclear localisation signal, mRNA modality and co-introduction of p53 dominant negative fragment to increase the transgene payload integration efficiency by up to 20-fold in defined genomic safe harbours in hPSCs.

"Similar papers" are the closest papers from that journal in the model's embedding space. They show what the match is built on, but the ranking comes mostly from a classifier over the whole training set, not from these examples alone.
