Kisspeptin-immunoreactive axons terminate near POMC neurons. A, A strong innervation by kisspeptin-immunoreactive axons is found in the arcuate nucleus. Scale bar, 12 μm. B, In the same field as in A, GFP-expressing POMC neurons are found. C, The arrows indicate kisspeptin-immunoreactive axons and boutons terminating near or on POMC neurons.
