Abstract
We isolated peripheral blood mononuclear cells from a patient diagnosed with early-onset non-syndromic retinitis pigmentosa caused by compound heterozygous mutations in CRB1 (NM_001257965): c.1369C>T (p.R457X) and c.2027C>T (p.T676M). These cells were transfected with four inducible plasmids encoding human OCT4, SOX2, KLF4 or C-MYC together. Transfected cells were induced to form pluripotent stem cells (iPSCs) expressing the pluripotent stem cell markers SOX2, OCT4, KLF4, SSEA4 and NANOG and presenting a normal karyotype. These cells could be differentiated into three germ layers as well as retinal organoids, and thus provide a valuable cellular model for the study of development of major retina diseases.
