| Last update | 21st August 2024 |
| Notes | This is a patient specific induced pluripotent stem cell (iPSC) line derived from a patient clinically diagnosed with Leber congenital amaurosis (LCA) and was found to carry a homozygous mutation in exon 7 of RPE65. The iPSC line has been generated by reprogramming of dermal fibroblast cells, using integration free episomal vectors viz; pCXLE-hOCT3/4-shp53-F, pCXLE-hSK and pCXLE-hUL (Addgene Plasmids #27077, #27078 and #27080 respectively). The line has been stably maintained beyond passage 20, and it expresses the stem cell markers OCT4, SOX2, NANOG, KLF4 and SSEA4, and has a normal karyotype. This line efficiently differentiates into all three germ cell lineages and also forms retinal organoids and mature pigmented RPE cells. |
