Researchers at the National Eye Institute (NEI), have developed a cryopreservation and cell recovery system designed specifically for the efficient cryopreservation, transportation and subsequent thawing of monolayers and tissues on a substrate. This closed cryopreservation/defrost system allows for sterility in addition to increased viability, recovery and safety of tissues that can be used for in vitro culture or surgical transplantation.
Researchers at the National Eye Institute have developed a new cytokine therapy that delivers functional interleukin 34 (IL-34) to the retina for treating ocular inflammatory diseases – such as uveitis and degenerative retinal diseases. Intraocular delivery of IL-34 protein or IL-34 gene expression system can effectively prevent retinal inflammation. Thus, it may be a promising strategy to produce long-lasting effects in suppressing abnormal retinal inflammation and preventing photoreceptor death.
