Immunocytochemical localization of different cell types in the adenohypophysis of the cichlid fish Cichlasoma dimerus (Heckel, 1840)
The adenohypophysis of the cichlid fish Cichlasoma dimerus was studied using the avidin-biotin-peroxidase method with antisera raised against piscine pituitary hormones and heterologous antisera against mammalian pituitary hormones. Antiserum raised against rabbit ACTH recognized a group of cells bo...
