The 2004 WHO classification of endocrine tumors defines pheochromocytoma as a tumor arising from catecholamine-producing chromaffin cells in the adrenal medulla -- an intra-adrenal paraganglioma.

this represents a specific maturational increase In LEU content per chromaffin cell. In adult medullae, decreasing transsynaptic activity through adrenal denervation or explantation results in a ...

Here we investigate the fate of single secretory vesicles after fusion with the plasma membrane by measuring capacitance changes and transmitter release in rat chromaffin cells using the cell ...
