Figure 4.

GAD67 expression in longitudinal slices of the mouse vertical crista. (A) Schematic representation showing the plane of the slice. Note that the section is not through the center of the crista (i.e., it is not a medial section). (B) Merged photomicrograph showing the expression of GAD67. Note the absence of GAD67 expression in the E.C. (white arrow). (C) Enlargement of a portion of the same image as in (B), showing in better detail the shape and position of the cells expressing GAD67. The white arrow points at the nuclear region of a supporting cell. The red arrow points at a nucleus of a hair cell.
