Generation of a human embryonic stem cell line, NERCe003-A-1, with lentivirus vector-mediated inducible CTNNB1 overexpression.

The human embryonic stem cell (hESC) line NERCe003-A-1 was generated by introducing lentiviral-vector-mediated tetracycline-inducible β-catenin expression into a normal hESC line, NERCe003-A. The resulting cell line can overexpress the β-catenin protein, encoded by the CTNNB1 gene, after exposure to doxycycline (Dox). CTNNB1 gene expression was confirmed by quantitative PCR (qPCR) and immunofluorescence assays. Further characterization confirmed that the NERCe003-A-1 cell line expresses typical pluripotency markers and has the ability to form the three germ layers both in vitro and in vivo.
