Schwann cells promote the survival of rat retinal ganglion cells after optic nerve section.
Schwann cells (SCs) are known to play an important role for the regeneration of mammalian peripheral nerves. Their effect is likely due to the production of neuronotrophic and/or supportive factors. Here we study the effect of intraocular transplant of SCs on the survival of rat retinal ganglion cells (RGCs) after the intracranial section of the optic nerve. SCs were injected intraocularly in a...
متن کاملEffect of NGF on the survival of rat retinal ganglion cells following optic nerve section.
The ability of NGF (2.5S subunit) to support the survival of adult rat retinal ganglion cells (RGCs) and optic nerve fibers after intracranial section of the optic nerve was investigated. NGF was injected intraocularly at a dose of 3 micrograms/injection every 2.3 d from the day of axotomy to analysis. Control animals received cytochrome c injections. The survival of RGCs was analyzed in whole-...
متن کاملThe neuroprotective effect of resveratrol on retinal ganglion cells after optic nerve transection
PURPOSE This study aimed to investigate the neuroprotective effect of resveratrol in an optic nerve transection (ONT) model and to identify the neuroprotective mechanism of resveratrol in retinal ganglion cells (RGCs). METHODS ONT and retrograde labeling were performed in Sprague-Dawley rats. Various concentrations of resveratrol were injected intravitreally immediately after ONT. The number ...
متن کاملAxons of retinal ganglion cells are insulted in the optic nerve early in DBA/2J glaucoma
Here, we use a mouse model (DBA/2J) to readdress the location of insult(s) to retinal ganglion cells (RGCs) in glaucoma. We localize an early sign of axon damage to an astrocyte-rich region of the optic nerve just posterior to the retina, analogous to the lamina cribrosa. In this region, a network of astrocytes associates intimately with RGC axons. Using BAX-deficient DBA/2J mice, which retain ...
متن کاملProtection of Pattern Electroretinogram and Retinal Ganglion Cells by Oncostatin M after Optic Nerve Injury
Injury to retinal ganglion cell (RGC) axons leads to selective loss of RGCs and vision. Previous studies have shown that exogenous neurotrophic factors promote RGC survival. We investigated the neuroprotective effects of oncostatin M (OSM), a member of the IL-6 family of cytokines, on pattern electroretinogram (PERG) and RGC survival after optic nerve crush (ON-crush) in the mouse. BALB/C mice ...
