Research on the Human Retinal Astrocytes is essential to the study of stroke, brain injury,Alexander disease, cerebellar degeneration, multiple system atrophy (MSA-C), glioblastoma invasion, and autoimmune cerebellar ataxia. The eye is a complex sensory organ that allows an organism to perceive visual information. It is composed of the eyeball and its accessory structures. The eyeball is the main visual organ, responsible for image formation and phototransduction. The accessory parts include the eyelids, conjunctiva, lacrimal apparatus, extraocular muscles, and the connective tissue within the orbit, which together protect and enable movement of the eyeball. The Human Retinal Astrocytes are to be used with Human Retinal Astrocyte Medium (Cat. No. ACM0111). This product is intended for laboratory in vitro use only. It is not intended for diagnostic, therapeutic, or clinical applications.
