How rod and cone photoreceptors are formed and could be regenerated
Mechanisms of cell fate specification and competence regulation in photoreceptors
This project aims to learn how immature retinal cells become rods or cones so future treatments might replace or regrow photoreceptors for people with macular degeneration and other vision-loss diseases.

What this research studies
Researchers will examine the gene networks and key switches that tell developing retinal cells to become rods, cones, or bipolar cells, focusing on factors called Otx2, Prdm1, and Vsx2. They will use lab-grown retinal cells and genetic experiments to see how changing these factors alters cell fate and competence. The team will explore strategies to reprogram cells in the diseased retina or to direct stem cells to become photoreceptors for possible transplantation. Findings are intended to guide future therapies for age-related macular degeneration and other conditions that cause photoreceptor loss.
Who could benefit from this research
Good fit: People with age-related macular degeneration or other diseases that cause loss of rod and cone photoreceptors would be the likely eventual candidates for therapies developed from this research.
Not a fit: Patients whose vision loss arises from optic nerve damage, severe retinal scarring, or conditions that do not primarily damage photoreceptors may not benefit from photoreceptor-targeted approaches.
Why it matters
Potential benefit: If successful, this work could lead to therapies that regenerate or replace lost rods and cones and potentially restore vision for people with photoreceptor loss.
How similar studies have performed: Related laboratory and animal studies have shown promise in producing photoreceptor-like cells from stem cells and reprogramming retinal cells, but clear vision-restoring results in humans remain unproven.
