(A–F) Confocal images (1-μm optical section) through the ovine ARC processed for dual immunofluorescence detection of OFQ (red) and either POMC, kisspeptin, AgRP, or TH (green). (C) Merged image of single-labeled OFQ neurons (A) and POMC neurons (B) to depict yellow dual-labeled OFQ/POMC neurons (eg, arrows). Note presence of a few single-labeled POMC neurons (eg, top-middle portion of B and C). Merged images in bottom row show OFQ and kisspeptin (Kiss) (D), AgRP (E), or TH (F). Magnification bar, 25 μm.
