Generation of an induced pluripotent stem cell line (LVPEIi002-A) with heterozygous RB1 mutation using peri-orbital fat derived mesenchymal cells of a patient with inherited retinoblastoma

Retinoblastoma is a pediatric intraocular cancer caused by biallelic inactivation of RB1 gene in retinal progenitor cells. Here, we report the generation of a patient-specific induced pluripotent stem cell (iPSC) line (LVPEIi002-A) from a patient diagnosed with retinoblastoma and showing familial inheritance of a nonsense mutation (c.1735C > T) within exon 18 of one of the two alleles. This RB1(+/-) iPSC line, LVPEIi002-A was generated by reprogramming the peri-orbital fat tissue derived mesenchymal cells and was stably expanded and characterized. It maintains the stemness, pluripotency, normal karyotype, and forms embryoid bodies comprising of all three lineage committed progenitor cells.
