Abstract:
Retinal degenerations and optic neuropathies often lead to death of photoreceptors or retinal ganglion cells, respectively. Stem cell therapies are showing promise for these diseases in preclinical models and are beginning to transition into human trials, but cell delivery and integration remain major challenges. Focusing on photoreceptor- and progenitor-directed approaches, in this article, the authors review how advances in tissue engineering and cell scaffold design are enhancing cell therapies for retinal degeneration.
Insights
Stem cell therapy shows promise for retinal diseases by improving cell delivery and integration. Advances in tissue engineering and scaffold design are key to enhancing these treatments for photoreceptor and progenitor cells.
