Polymeric scaffolds are revolutionizing therapeutics for blinding disorders affecting the outer retina, a region anatomically and functionally defined by light-sensitive photoreceptors. Recent engineering advances have produced planar scaffolds optimized for retinal pigment epithelium monolayer delivery, which are being tested in early stage clinical trials.

UW vision researchers partner with U.S. Department of Defense to develop stem cell therapy for combat-related eye injuries

The new project, titled Outer Retina Reconstruction for Combat Afflictions or ORRCA, is a collaboration between the McPherson Eye Research Insitute at UW‒Madison, the UW School of Medicine and Public Health, the UW College of Engineering, the University of Birmingham (UK) and British Ministry of Defence and the National Eye Institute. It is funded by a grant for more than $5 million from the U.S. Department of Defense (DOD).

Numerous protocols have been described that produce neural retina from human pluripotent stem cells (hPSCs), many of which are based on the culture of 3D organoids. While nearly all such methods yield at least partial segments of highly mature-appearing retinal structure, variabilities exist within and between organoids that can change over a protracted time course of differentiation.

Cell type-specific investigations commonly employ gene reporters or single-cell (sc) analytical techniques. However, reporter line development is arduous and generally limited to a single gene of interest, while scRNA-seq frequently yields equivocal results that preclude definitive cell identification.
