Although extensive research has been conducted on neuroprotection for retinal ganglion cells, there is still no treatment for clinical use. Recent evidence shows that extracellular vesicles isolated from a variety of stem cells are efficacious in retinal ganglion cell neuroprotection. In this study, we tested the novel extracellular vesicle source of the retinal progenitor R-28 cell line\n                    <jats:italic toggle=\"yes\">in vitro<\/jats:italic>\n                    and\n                    <jats:italic toggle=\"yes\">in vivo<\/jats:italic>\n                    .

Additionally, we tested extracellular vesicles for their neuroprotective capacity in retinal ganglion cells differentiated from human embryonic stem cells. Finally, we investigated miRNA changes in retinal ganglion cells with R-28 extracellular vesicle treatment, and predicted possible pathways that may be modulated. R-28 extracellular vesicles improved retinal ganglion cell survival but failed to preserve axons significantly. Moreover, the results also illustrated the neuroprotection of R-28 extracellular vesicles on human retinal ganglion cells. Finally, we also showed changes in hsa-miRNA-4443, hsa-miRNA-216a-5p, hsa-let-7e-5p, hsa-miRNA-374b-5p, hsa-miRNA-331-3p, and hsa-miRNA-421 expressions, which may have neuroprotective potential on retinal ganglion cell degeneration. This study will pave the way for miRNA and extracellular vesicle-based neuroprotective therapies for glaucoma.\n
