Fig. 1From: Regulation of kisspeptin and gonadotropin-releasing hormone expression in rat placenta: study using primary cultures of rat placental cellsStaining of rat placental cells for GnRH and kisspeptin. Cultures of placental cells from rats at 18 weeks of gestation were immunostained using anti-kisspeptin (Kp-10) (b) and anti-GnRH (c) antibodies. The negative control is shown in (a) (control). The colors were developed by streptavidin-biotinylated horseradish peroxidase. Magnification, ×20Back to article page
