Generation of two H1 hESC sublines carrying deletions of RB1 exon 1/promoter in heterozygous or compound heterozygous state

摘要

Biallelic inactivation of the retinoblastoma tumor suppressor gene (RB1) causes formation of retinoblastoma, a retinal eye tumor occurring in early childhood. Using the CRISPR/Cas9 nickase system, exon 1 of RB1 was deleted, including the RB1 promoter. As a result, sublines were generated carrying deletions of RB1 exon 1/promoter on one or both alleles.
