Groups of DCX-positive cells in the rat brain are limited to a few sites including the ventral SCN. A. Brain atlas image showing the SVZ and the SCN. B. Photomicrograph of DCX immunoreactivity within the region boxed in A. Note that groups of DCX+ cells are located only in the SVZ and SCN. Scale bar below image = 300 μm. C & D. Photomicrographs of DAPI-labelled and DCX-immunoreactive cells showing the location of DCX-immunoreactive cells within the ventral region of the SCN. Note the presence of some DCX-immmunoreactive cell bodies that are embedded in the optic chiasm. Scale bar = 50 μm. E. 20 μm. Abbreviations: 3V, third ventricle; OC, optic chiasm; SVZ, sub-ventricular zone.
