The major septal receptor genes are also expressed in the MOE and concentrated in certain areas. A, Different zones (zone 1 in green and zone 4 in blue) are approximately indicated in an MOE hemisection. Pictures B–D were taken approximately from the area within the rectangle. B–D, The mid-anteroposterial MOE sections were hybridized with the following antisense RNA probes: MOR256-3 (B), MOR244-3 (C), and MOR232-2 (D). E, Most of the major septal olfactory receptor genes are also concentrated in the areas indicated by red lines within zone 4. Ecto 2, Ectoturbinate 2. F1, F2, The MOE sections were hybridized by FLU-labeled OMP (green) and DIG-labeled (red) probes containing MOR256-2, MOR244-3, MOR235-1, MOR160-2, MOR236-1, MOR244-2, MOR271-1, and MOR232-2. Two images (F1, F2) were taken in the areas indicated in E. The white lines in F2 indicate relatively “cold areas”, where fewer cells were labeled.
