Summary
This review examines stem cell-derived retinal organoid models and advanced coculture techniques that replicate the RPE-photoreceptor interface, which is critical for understanding diseases like age-related macular degeneration. While not directly focused on lighting design, it provides foundational insight into retinal cell biology relevant to understanding photoreceptor vulnerability and the ocular health implications of light exposure.
Key Findings
- Current retinal organoids lack a representative RPE-photoreceptor interface and vascular elements, limiting their utility for modeling common retinal diseases such as age-related macular degeneration.
- Advanced coculture techniques incorporating RPE-photoreceptor and RPE-Bruch's membrane-choriocapillaris interactions can overcome key limitations of existing organoid models for disease modeling and regenerative therapy optimization.
- Several transplantation strategies—including minimally invasive delivery, biocompatible material vehicles, retinal cell sheets, and optogenetics—are identified as promising approaches to improve graft integration and functionality.
