Fig. 3. Unaltered distribution of NADHPd-positive glomeruli in RNCAM transgenic mice. (A-F) Histochemistry analyzes of NADPHd activity (black) in the OB. (A-C) Dorsal views of whole-mount OB preparations; control mouse (A), GpiRNCAM transgenic mouse (B) and TmRNCAM mice (C). (D-F) Coronal sections of the OB at a rostrocaudal position indicated by a broken line in A-C from control mouse (D), GpiRNCAM transgenic mouse (E) and TmRNCAM transgenic mice (F). Although the intensity and exact position of NADPHd-positive glomeruli varied between individual mice in an RNCAM-independent manner, both control and RNCAM-transgenic mice showed an identical general topography of NADPHd-positive and NADPHd-negative OB regions.
