Generation Of An Nans Homozygous Knockout Human Induced Pluripotent Stem Cell Line By The Insertion Of Gfp-P2a-Puro Via Crispr/Cas9 Editing

N-acetylneuraminic acid synthase (NANS), the gene encoding the synthase for N-acetylneuraminic acid (NeuNAc; sialic acid), is closely associated with infantile-onset severe developmental delay and skeletal dysplasia. However, the role and the involved mechanisms of NANS functioning have not been fully understood to date. Here, we generated a homozygous NANS-knockout human induced pluripotent stem cell (iPSC) line, NCCSEDi001-A-1, via the CRISPR/Cas9-based gene editing method. The NCCSEDi001-A-1 cell line does not express NANS protein, but maintains a normal karyotype, pluripotency, and trilineage differentiation potential.
