Figure 3.
Distribution of VPAC1 (green) and oxytocin (OXT; red) immunoreactivity in the mid and rostral part of SCN and PVN in a wild-type mouse. Images (A–F) represent maximal projections of 16 digital sections in a Z-stack (Z = 2 μm). (A,B) show immunoreactivity for VPAC1 in the rostral and mid part of PVN. (C,D) show immunoreactivity for OXT in the rostral and mid part of PVN. Colocalization between VPAC1 and OXT in the rostral and mid part of PVN is visualized in (E,F) using IMARIS colocalization module (see “Materials and Methods” section). Scale bars: (A–F) = 80 μm.
