The adenohypophysis of the swamp eel, Synbranchus marmoratus, an immunocytochemical analysis
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 pa...
