Generation of RYBP FLAG-HA knock-in human embryonic stem cell line through CRISPR/Cas9-mediated homologous recombination

[摘要] RYBP, a critical component of polycomb repressive complex1 (PRC1), is required for the pluripotency and differentiation of mouse embryonic stem cells(mESCs). However, its function and mechanism to regulate human embryonic stem cells(hESCs) remain unknown. Here, to investigate the role of RYBP in hESCs, we generate an hESC line with FLAG-HA tag knock-in to RYBP locus through CRISPR/Cas9-mediated homologous recombination. hESC with RYBP _FLAG-HA knock-in maintains normal morphology and karyotype, while it maintains pluripotency to differentiate into three germ layers.
