Duke Engineers Regenerate Mouse Retinas Using Stem Cells, Restores Vision

7/1/2026

Summary

Duke Engineers Regenerate Retina

Duke University biomedical engineers injected iPSC-derived retinal endothelial cells into damaged mouse retinas, where the cells integrated and regenerated vessels.
The integration restored retinal function in the mice.
The team also fabricated functional retinal vascular tissue in vitro to serve as a disease-modeling platform.
The work, funded by the National Eye Institute and NASA, was published online June 30, 2026 in Nature Biomedical Engineering.

Summary

Esswein Scales Retina

The protocol uses commercial stem cells and a defined growth-factor mix, which could dramatically lower retinal cell production costs.
Because the cells derive from a standardized GMP-compatible line, regulatory approval for therapies may become more straightforward.
The unlimited, on-demand supply could replace scarce donor tissue and speed eye-drug screening worldwide.
PhD student Parker Esswein said the scalable method lets labs build disease models without costly tissue procurement.
