The adenohypophyseal cell types of the protogynous fish Synbranchus marmoratus were studied by histochemical and immunocytochemical staining with antisera raised against piscine and human pituitary hormones to ascertain their distribution. The prolactin (PRL) cells were distributed in the rostral pars distalis and showed specific binding to antisera to carp and chum salmon prolactin. No reaction was observed with antiserum to human prolactin. The corticotrops showed strong immunoreactivity with anti-human ACTH, these cells bordered the neurohypophysis and islets between PRL cells in the rostral pars distalis. Growth hormone (GH) cells were densely distributed and associated with the neurohypophysis only in pars distalis proximal. They reacted with antisera to piscine GH but not with antisera to human growth hormone. The thyrotrops were scattered in the proximal pars distalis and showed strong immunoreactivity to the human thyrotropin Beta subunit antiserum. Gonadotrops were located in the central area of the proximal pars distalis and in the external border of the pars intermedia. These cells were alcian blue and PAS positive, and reacted with anti-croaker GTH and anti-coho GTH I and GTH II. The PAS positive cells from the pars intermedia bound specifically to anti-chum somatolactin.
