Fig. 1. Emx2 is expressed in progenitors of both the adult dentate gyrus of the hippocampus and the forebrain subventricular zone (SVZ). (A,B) Emx2 mRNA is present in (A) the adult hippocampus and (B) the dentate gyrus. (C) Strong expression of the gene could be observed along the rostral migratory stream (RMS) that extends toward the two olfactory bulbs and (D) in the periventricular region that lines the lateral ventricles. (E) Cells expressing Emx2 messenger appear to be localized in the subventricular layer (arrow). V, ventricle; Str, striatum; SVZ, subventricular zone; dg, dentate gyrus; h, hilus; dgc, dentate granule cells.
