The ultrastructure of hypertrophied paraganglia in aged rats.

Abstract

The catecholamine-storing cells in the paraganglia of old rats showed structural characteristics common to adrenomedullary and paraganglionic cells of young animals. No sign of degeneration was found. Lipofuscin pigment was observed in most cells. The paraganglia were innervated and well supplied by fenestrated sinusoidal capillaries. Their fine structure suggests active endocrine function. An increase in the total bulk of the paraganglia in old rats suggests that they have a physiological role in senescence.
