Stem Cells and Retinitis Pigmentosa: A Roadmap Toward Restoring Retinal Cells

A 2026 review explores how stem cells, extracellular vesicles, and retinal organoids could support retinal repair in retinitis pigmentosa and other degenerative eye diseases. The field is promising, but challenges such as cell survival, immune rejection, integration, and long-term safety remain before these approaches can become routine care.
