Abstract
Antisera raised to highly purified tilapia (Sarotherodon mossambicus) prolactin (PRL) and growth hormone (GH) were used to locate PRL and GH cells in the adenohypophysis of seven species of teleosts by immunoenzymological methods using horseradish peroxidase. The only pituitary cells in the tilapia that immunologically reacted with anti-tilapia PRL were the PRL cells located in the rostral pars distalis (RPD). In the pituitary glands of two species of salmonids and two species of marine fishes, the tilapia PRL antibodies bound to both PRL and GH cells; no prolactin-immunoreactive cells were identified in the goldfish and eel pituitaries. Antiserum to tilapia GH reacted specifically with the GH cells located in the proximal pars distalis of all teleosts examined in this study, but not with any presumed PRL cells in the RPD. These results indicate that tilapia PRL antisera are specific for tilapia PRL cells but not necessarily for these cells in other teleost species. Tilapia GH antisera showed no species specificity among the teleosts tested.
