Abstract:
Because retinal cells could not regenerate in mammals, retinal degeneration is an irreversible phenomenon caused by various disease conditions including age-related macular degeneration (AMD) and retinitis pigmentosa (RP). During the course of these diseases, photoreceptors (PRs) are susceptible to degenerate due to their malfunctions or to a primary dysfunction of the retinal pigment epithelium (RPE). These diseases affect millions of individuals worldwide. Many therapies currently under development are designed to treat retinal pathologies and among those, cell-based replacement strategies hold significant promise for treatment of retinal degenerative diseases, especially when atrophy of retinal tissue occurs. This review will focus on the use of hPSCs to slow-down or treat retinal disorders and discuss current challenges to achieve successful engraftment of cell products.
Insights
Retinal degeneration is irreversible, but human pluripotent stem cells (hPSCs) offer hope for cell-based therapies to restore vision. Challenges remain in achieving successful cell engraftment for treating retinal disorders.

- These conditions affect millions globally, necessitating novel therapeutic strategies.
- Current research focuses on cell-based replacement therapies as a promising approach for retinal tissue regeneration.
Approach:
- This review explores the application of human pluripotent stem cells (hPSCs) for treating retinal disorders.
- It examines the potential of hPSCs in slowing or reversing retinal pathologies.
- The review discusses the critical challenges associated with achieving successful engraftment of hPSC-derived cell products.
Key Points:
- Human pluripotent stem cells (hPSCs) are being investigated for their potential in treating irreversible retinal degenerative diseases.
- Cell-based replacement strategies using hPSCs show promise, particularly for conditions involving retinal tissue atrophy.
