Ultrastructural and biochemical characterization of catecholamine release mechanisms in cultured human pheochromocytoma cells.

OBJECTIVE To characterize ultrastructurally and biochemically catecholamine release mechanisms of cultured human pheochromocytoma cells in the basal and stimulated states. METHODS The cultured pheochromocytoma cells were prepared from human adrenal pheochromocytoma tumors. Biochemical determinations of catecholamine secretion from the cultured cells were… CONTINUE READING
