Representative photographs showing colocalization of ghrelin receptors (Ghs-r) and Prcp mRNA in the hypothalamic ARC, VMH, DMH, LH and the CTX, by double fluorescent in situ hybridization. Red and green represent Ghs-r- and Prcp-expressing cells, respectively. Merged images show co-labeled cells producing both Ghs-r and Prcp. 3v: third ventricle. Bar scale represents 30 μm for all panels. (For interpretation of the references to color in this figure legend, the reader is referred to the web version of this article.)
