Figure 3
Sections hybridized with cRNA for trkB (A-B) and trkC (C-D).  High levels of trkB mRNA are seen in the developing olfactory bulb (dOB) by E14 (A), and by E16 (B) expression is higher in the outer layer (B). TrkC cRNA labels most of the brain at E14 (C) and E16 (D), including the bulbs.  At E16 (D), the mesoderm (m) under the olfactory epithelium is densely labeled. LV, lateral ventricle; BTel, basal telencephalon; Tg, tegmentum.
