Generation of 3X FLAG-tagged human embryonic stem cell (hESC) line to study WNT-induced β-catenin DNA interactions (HVRDe009-A-2)


In the canonical WNT signaling pathway, active WNT signaling results in the nuclear translocation of β-catenin where it regulates target gene expression. As a tool to understand these β-catenin DNA interactions, we used a CRISPR/Cas9 based approach to engineer a human embryonic stem cell line (hESC) harboring a 3X FLAG sequence fused to the C-terminus of β-catenin. Engineered cells displayed a characteristic hESC morphology, expressed pluripotency-associated markers, retained tri-lineage differentiation potential, and had a normal euploid karyotype. This cell line represents a valuable tool to dissect the transcriptional mechanisms by which WNT signalling regulates pluripotent cell fate. Copyright © 2021 The Authors. Published by Elsevier B.V.
