Gonadotropic and thyrotropic cells from the Mediterranean Yellowtail (Seriola dumerilii; Risso, 1810): Immunocytochemical and ultrastructural characterization

Abstract

Gonadotropes that are of a single morphological type but that vary in ultrastructure are present in the pituitary of captive M. yellowtail. GTH II- and putative GTH I-producing cells were distinguishable from one another and from TSH cells by their different reactions to anti-My alpha,betaGTH II, anti-My betaGTH II, and anti-My alpha,betaGTH II preabsorbed with the My alphaGTH-subunit.
