WT1 and retinitis pigmentosa: To investigate the ability of fibroblast‐derived iPSC lines to generate retinal organoids, we differentiated three fully characterized iPSC lines from unaffected donors (referred thereafter as WT1, WT2, and WT3) 34, one iPSC line from a donor with age related macular degeneration (referred thereafter as AMD) 35 and one iPSC line from a subject with retinitis pigmentosa (referred thereafter as RP 33 using the induction‐reversal protocol developed by Kuwahara et al. in hESC for cogeneration of neural retina and RPE 36.
