Figure 3.
These images show the distribution of lacZ-labeled cells in histological sections (B,C,E), wholemounts (A,D), BDNF (A,B,D,E), and NeuroD (C). These images show the similarities in distribution of NeuroD and BDNF inside the utricle as well as in delaminating cells (B,C). The wholemounts show the distribution of BDNF in forming hair cells inside the saccule and utricle as well as the delaminating cells converging from specific areas of these sensory epithelia toward the forming vestibular ganglion (A). Such cells delaminate as late as E17 from the hair-cell-free hilus region of the utricle that is filled with hair cells only after completion of this delamination (D,E). Bar indicates 100 μm.
