Two hormones with lactogenic activity are produced by the hamster placenta during the second half of pregnancy. One of these hormones, hamster placental lactogen II (haPL-II), has been well characterized; however, its cellular source is not known. In the present study, haPL-II was localized in placental tissues using a specific antibody and the avidin-biotin-peroxidase immunohistochemical technique. Because relaxin has been localized in the hamster placenta, it was of interest to determine if haPL-II and relaxin are localized in the same cells. haPL-II immunoactivity was observed in primary and secondary giant trophoblast cells of the placenta on Days 12, 14, and 15 of pregnancy. On Day 15 positive staining was also observed in large cells located within mesometrial arteries and in eosinophilic bodies associated with degenerating sheathed arteries of the decidua basalis. haPL-II-positive staining was not observed in placentae from Days 8 or 10 of pregnancy. On Day 14, haPL-II was colocalized with relaxin in 75% of the giant trophoblast cells observed. Therefore, it is probable that these hormones are synthesized and secreted by the same cell.
