In this protocol, retinitis pigmentosa patient induced pluripotent stem cell (iPSC)-derived 3D retinal organoids were generated. Those organoids successfully recapitulated some clinical phenotypes of the retinitis pigmentosa disease.

Retinitis pigmentosa (RP) is a rare and inherited retinal degenerative disease with a prevalence of approximately 1/4,000 people worldwide. The majority of RP patients have progressive photoreceptor degeneration leading to peripheral vision loss, night blindness, and finally, total blindness. To date, thousands of mutations in more than 90 genes have been reported to be associated with RP. Currently, there are few animal models available for all the affected genes and different types of mutations, which largely hampers the deciphering of the mechanisms underlying the gene/mutation pathology and limits treatment and drug development. Patient induced pluripotent stem cell (iPSC)-derived 3D retinal organoids (ROs) have provided a better system to model the human early-onset disease than cells and animals. In order to study RP, those patient-derived 3D retinal organoids were utilized to recapitulate the clinical phenotypes of RP. In the RP patient-derived ROs, Rhodopsin mislocalization was clearly displayed. Compared with other animal models, patient iPSC-derived retinal organoid models more closely recapitulated RP features and represent an ideal approach for investigating the disease pathogenesis and for drug development.

Human retinal diseases, such as retinitis pigmentosa and age-related macular degeneration, are poorly understood due to the lack of appropriate experimental models1,2. Although the mouse retina is very similar to the human retina and is a powerful tool for studying the etiology of retinal degeneration, there are huge species differences between mice and humans3,4. For instance, the nuclear architecture of the photoreceptor cells in mice and humans is different, and the mouse retina does not possess a macula5,

1. Cell culture and generation of iPSCs

  1. Choose RPGR patients for this study. Here, three patients, one familial carrier and three healthy controls, were used. Patient 1 possessed a mutation c.1685_1686delAT in exon 14 of the RPGR gene, patient 2 harbored a mutation c.2234_2235delGA in exon 15 of the RPGR gene, and patient 3 had a mutation c.2403_2404delAG in exo.......

The schematic illustration describes the differentiation procedures to generate healthy and patient iPSC-derived retinal organoids (Figure 1). From iPSC to ROs, variations can be produced owing to several factors. The status of the iPSC is the determinant step of the RO generation. In addition, it is highly recommended that researchers should record every step, catalog, and lot number of all media so that the entire experiments are trackable. In Figure 2A, the i.......

Retinal organoids are 3D, laminated structures derived from hiPSCs or embryonic stem cells (ESCs) and feature as a very promising model to mimic the spatial and temporal patterns of human retinal development31,32. The ROs consist of various types of retinal cells, including photoreceptors, bipolar cells, ganglion cells, amacrine cells, horizontal cells, and Müller glia33. 2D culture cannot precisely mimic the orientation and developme.......
