title: The sheep pars tuberalis: an immunohistochemical study. Demonstration of the presence of glycoprotein and lipotropin hormones.
abstract: Using indirect immunofluorescence with fourteen different antisera raised against pituitary hormones and peptides, we characterized immunochemically the cells of the sheep pars tuberalis. The presence of LH- and FSH-containing cells, shown in previous studies, was also observed in the present investigation. In addition, we found TSH-containing cells, never observed in sheep, and beta LPH-containing cells. The latter hormone has never been found in any studied species. It appeared that a small amount of perikarya (less than 20%) were immunolabelled and, that the sheep pars tuberalis contained a majority of immunonegative cells as in the guinea-pig rabbit and rhesus monkey. This study may contribute to a better knowledge of the function of the sheep pars tuberalis.
