Generation of an ELTD1 knockout human embryonic stem cell line by the iCRISPR/Cas9 system.

Human ELTD1 (Epidermal growth factor, latrophilin and seven-transmembrane domain-containing 1), an orphan G-protein-coupled receptor (GPCR) belonging to the adhesion GPCR family, has been reported as a novel regulator of angiogenesis and a potential anti-cancer therapeutic target. However, little is known about the function of ELTD1, especially its undiscovered ligands. In this experiment, an ELTD1 homozygous knockout human embryonic stem cell line, FAHZUe001-A, was generated by the iCRISPR/Cas9 system to achieve a deeper understanding of ELTD1. The FAHZUe001-A was confirmed with normal karyotype, typical undifferentiated morphology, pluripotency and trilineage differentiation potential in vitro.
