Micrograph exhibiting the absence of kisspeptin and prodynorphin coexpression in cells of the ARC in a P30 car feminine rat. The part was imaged (Plan Fluor DIC 40× [oil]) for triple-labeling of kisspeptin (inexperienced), neurokinin B (blue), and prodynorphin (pink). White arrows point out neurons co-expressing kisspeptin and neurokinin, and grey arrows point out a separate inhabitants of neurons expressing prodynorphin. Scale bar, 25 μm.
