      The CRISPR–Cas system is a powerful genome editing tool that functions in a diverse array of organisms and cell types. The technology was initially developed to induce targeted mutations in DNA, but CRISPR–Cas has now been ...
    • Chromatin accessibility established by Pou5f3, Sox19b and Nanog primes genes for activity during zebrafish genome activation 

      Pálfy, Máté; Schulze, Gunnar; Valen, Eivind; Vastenhouw, Nadine L. (Journal article; Peer reviewed, 2020-01)
      In many organisms, early embryonic development is driven by maternally provided factors until the controlled onset of transcription during zygotic genome activation. The regulation of chromatin accessibility and its ...
    • Efficient CRISPR-Cas9-mediated generation of knockin human pluripotent stem cells lacking undesired mutations at the targeted locus 

      Merkle, Florian T.; Neuhausser, Werner M.; Santos, David; Valen, Eivind; Gagnon, James A.; Maas, Kristi; Sandoe, Jackson; Schier, Alexander F.; Eggan, Kevin (Peer reviewed; Journal article, 2015-05)
      The CRISPR-Cas9 system has the potential to revolutionize genome editing in human pluripotent stem cells (hPSCs), but its advantages and pitfalls are still poorly understood. We systematically tested the ability of CRISPR-Cas9 ...
