Figure 8.

Epifluorescence whole-mount images of bulbs of transgenic mice expressing rat OR I7 from a mouse MOR23 promoter and gap-YFP with and without Nrp1. Images of medial and lateral views of bulbs were taken with a Nikon SMZ25 stereomicroscope. Signal represents the intrinsic fluorescence of YFP. Dorsal is up, ventral is down. A, Views on the medial and lateral aspects of a left bulb (left two images) and a right bulb (right two images) of two I7-Cre-YFP Tg mice at PD17. Axons coalesce into a single glomerulus. B, Views on the medial and lateral aspects of the right bulbs of six I7-Cre-YFP Tg × n5247-flox littermates at PD14. Images are pairwise for an individual mouse. Glomeruli are indicated with yellow arrows. Axons coalesce into multiple glomeruli, in particular in the lateral aspect.
