(A,C,E,E`) p150a in situ hybridization shows ubiquitous expression at 1 and 2 dpf, with a slight enrichment in neurons of the pLL ganglion at 4 dpf. (B,D,F,F`) p150b is enriched in developing neurons with low level expression ubiquitously at all stages assayed. pLL and anterior lateral line ganglia are indicated by an arrowhead or arrow respectively in all. *=ear. Higher magnification views of the ear, pLL ganglia, and anterior lateral line ganglia shown in insets in B`, D`, E`, and F`. Scale bars in A-F = 100 µm. Scale bars in B` and D`-F`=20 µm.
