Telomeric repeat binding factor 1 (TRF1) plays an essential role in maintaining telomere length. Here, we established TRF1-knockout human pluripotent stem cells (hPSCs; hTRF1-KO) using the CRISPR/Cas9 technology. The hTRF1-KO cell lines expressed pluripotency markers and demonstrated a normal karyotype (46, XX) and DNA profile. In addition, hTRF1-KOcells spontaneously differentiated into all three germ layers in vitro. Thus, these cell lines could be useful models in various research fields.
