Abstract: | Summary Gonadotroph-rich cell lines were established from multipotential pituitary clonal cells (2A8) which were implanted under kidney capsule of hypophysectomized female rats. These cell lines secrete gonadotrophins (FSH and LH) continuously over two months after establishment; LHRH stimulated the secretion of hormones into the culture medium. Many of the cells reacted immunohistochemically to antiserum to FSH or LH, while a small number reacted to antiserum to prolactin or TSH. They did not contain normal secretory granules such as those of gonadotrophs in vivo.Supported by USPHS Grant HD 11826 and NIH Grant P30 HD 10202. The authors wish to thank James Chambers (Immunocytochemistry), and Pat Koym and John Rhode (Radioimmunoassay) for their excellent technical assistance. We also express our thanks to NIAMDD for providing pituitary hormones |
