Figure 1. Double in situ hybridization of pMCH and histamine receptors in the lateral hypothalamus of the rat and mouse.
Sections hybridized with antisense 35S-labelled riboprobes (black grains) for histamine receptors and DIG-labelled MCH precursor (pMCH) (purple). A and B, H1R antisense probes in the rat and mouse, respectively. C and D, H2R antisense probes in the rat and mouse, respectively. E and F, H3R antisense probes in the rat and mouse, respectively. G and H, H3R sense probes in the rat and mouse, respectively. Black arrows show examples of colocalization; white arrows indicate cells that do not colocalize. Scale bars: 50 μm.
