Abstract
Conditions have been established which allow growth of embryonic rat retinal cells in dissociated cell culture for up to one month. Na+,K+-ATPase localization was stuied in both neuronal and mixed neuronal-glial (flat cell) cultures. High Na+,K+-ATPase-like-immunoreactivity was associated with plasma membranes of neuronal cell bodies and their processes. Markedly lower immunoreactivity was found in the underlying flat cells in mixed cultures. Staining was generally uniform over perikaryal plasma membranes and showed a bead-like appearance in neuronal processes, supporting previous studies in brain tissue which used histocytochemical procedures specific for the Na+,K+-ATPase. This system should be useful for examining distribution of the enzyme in developing nerve and glial cells and may help to resolve questions regarding Na+−K+ homeostasis by neurons and glia.
