Immunocytochemical technique for detection of prolactin (PRL) and growth hormone (GH) in hyperplastic and neoplastic lesions of dog prostate and mammary gland
Abstract
An immunocytochemical technique was described to test for immunoreactive prolactin (PRL) and growth hormone (GH) in spontaneous and experimentally induced hyperplastic and neoplastic lesions of the prostate and mammary gland. The dog was used as an animal model. The specificity and validity of the immunocytochemical staining procedure and of the antisera to canine PRL and canine GH can be regarded as established for the demonstration of PRL- and GH-dependent staining respectively. In mammary and prostatic tissues, both endogenous PRL and GH as well as intracellular free binding sites (for exogenous PRL and GH) were detected immunocytochemically. The technique presented seems to be an important tool to localize putative target sites for pituitary hormones in hormone-dependent hyperplasia and neoplasia.
