Top. Changes in expression of a lacZ reporter construct inserted into the NT-3 locus. Whole mounts of heterozygous animals (see text). A, E9.5: staining is observed in the first branchial arch (arrow) and the anterior (a) and posterior (p) neuropores of the mesencephalon. B, E10.5 counterstained for TuJ1 to show axonal projections. The lacZ reaction was underdeveloped to allow visualization of axons. C, E11.5 embryo. Expression of NT-3 is strongest at the distal half of the maxillary process (Mx). D, E13.5 embryo. Reporter expression in the maxillary territory is strongest in the mystacial pad (MP) and distinctly less elsewhere.
