Immunocytochemistry of gonadotropic cells in the pituitary of Pomadasys jubelini (teleost fish).
An antibody specific for the beta subunit of carp gonadotropin was applied to pituitary sections from Pomadasys jubelini in order to characterize and localize the gonadotropic cells by immunocytological means. It reveals the gonadotropic zone lying mainly at the periphery of the proximal pars distalis with lateral extensions around the pars intermedia. The separation between the pars proximalis and the pars intermedia is irregular. Short finger-like extensions of the gonadotropic zone protrude more or less into the pars intermedia. The immunocytological results corroborate previous tentative identifications of the gonadotropic cells by classical cytological methods and suggest that the gonadotropic hormone produced is immunologically related with several previously studied fish gonadotropins.
