Figure 4

p75^−/−mice show less of an increase in geniculate ganglion size with embryonic age. Anti-β-III tubulin antibody labeling of the geniculate ganglion (arrows) in wild-type (A,C,E,G) and p75^−/−(B,D,F,H) mice. Beginning on embryonic day (E) 14.5 the ganglion appears to be slightly reduced in size in p75^−/−mice compared with wild-type mice. Scale bar = 100 μm.
