Abstract: A method of improving the survival of neuronal cells has the steps of obtaining a frozen cellular composition comprising neuronal cells; thawing the cellular composition; and contacting the cellular composition with a balanced electrolyte solution including a lithium salt. One example of a lithium salt is lithium chloride. Also is provided a kit comprising a container of with a cellular composition comprising neuronal cells and a container of a diluent comprising a balanced electrolyte solution and a lithium salt.

Abstract: Disclosed herein is the treatment of vision loss in a mammal by transplanting an effective amount of hNT-Neuron cells. The treatment can be accomplished by injecting the cells into the retinal area of the eye. Additionally, the cells can be injected into the visual cortex of the brain. Conditions to be treated are vision loss due to optic nerve damage, including glaucoma, optic nerve sheath meningioma and glioma, Graves' ophthalmopathy, benign or malignant orbital tumors, metastatic lesions, tumors arising from the adjacent paranasal sinuses or middle cranial fossa, giant pituitary adenomas, brain tumors or abscesses, cerebral trauma or hemorrhage, meningitis, arachnoidal adhesions, pseudotumor cerebri, cavernous sinus thrombosis, dural sinus thrombosis, encephalitis, space-occupying brain lesions, severe hypertensive disease or pulmonary emphysema.
