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.
端粒重复结合因子 1(TRF1)在维持端粒长度方面发挥着重要作用。在这里,我们使用 CRISPR/Cas9 技术建立了 TRF1 敲除的人类多能干细胞(hPSCs;hTRF1-KO)。hTRF1-KO 细胞系表达多能性标记物,并表现出正常的核型(46,XX)和 DNA 图谱。此外,hTRF1-KO 细胞在体外自发分化为三个胚层。因此,这些细胞系可以成为各种研究领域的有用模型。
