Summary
Pluripotent stem cell-derived retinal pigment epithelium (pRPE) offers a promising regenerative therapy for retinal diseases like age-related macular degeneration (AMD). This review covers pRPE derivation, transplantation, and challenges in developing functional RPE tissue.
Area of Science:
- Ophthalmology and Regenerative Medicine
- Stem Cell Biology and Tissue Engineering
Background:
- The retinal pigment epithelium (RPE) is vital for vision, forming the blood-retina barrier and supporting photoreceptors.
- RPE dysfunction and loss are implicated in degenerative diseases such as age-related macular degeneration (AMD).
- Pluripotent stem cell-derived RPE (pRPE) presents a potential regenerative therapeutic strategy for RPE-related diseases.
Conclusions:
- Understanding RPE differentiation is key for successful stem cell-based RPE derivation.
- Overcoming limitations in in vitro RPE culture is crucial for developing functional RPE tissues for transplantation.
- pRPE transplantation holds promise for treating RPE-related retinal degenerations, with ongoing clinical investigations.

The ability of induced pluripotent stem cells or iPSCs to differentiate into most body cell types has stimulated repair and regenerative medicine research over the past few decades. iPSC-derived blood cells, hepatocytes, beta islet cells, cardiomyocytes, neurons, and other cell types can repair injuries or regenerate damaged tissue in diseases such as diabetes and neurodegenerative disorders.

Stem cells are undifferentiated cells that divide and produce different types of cells. Ordinarily, cells that have differentiated into a specific cell type are post-mitotic—that is, they no longer divide. However, scientists have found a way to reprogram these mature cells so that they “de-differentiate” and return to an unspecialized, proliferative state. These cells are also pluripotent like embryonic stem cells—able to produce all cell types—and are therefore...
