A semiquantitative immunohistochemical technique was developed for identification of chick progesterone receptor (PR). The mouse monoclonal antibody PR6 was used. The nuclear PR concentration was analyzed with Leitz Orthoplan MPV-3 light microscope. The target tissue was chick oviduct, with epithelial, glandular, mesenchymal, smooth muscle and peritoneal cells analyzed separately. PR concentration varied between different cell types and also from cell to cell within a single cell type. A significant decrease of PR concentration, as noted by decrease in staining, was also observed in all studied cell types, 6 h after a single injection of progesterone. This technique allows for histological identification of biochemical events that should help lead to the understanding of the role of PR changes in a variety of experimental situations.
