Sodium and calcium action potentials in human anterior pituitary cells.
Human anterior pituitary cells derived from a somatotropin-secreting adenoma were capable of generating action potentials with Ca2+ and tetrodotoxin-sensitive Na+ components. A major fraction of the action current was carried by Na ions.
