PGCs expressed SOX10, SOX9 and S100B in the W9 human fetal cochlea.

<p>(A–E) Confocal images of a cochlea at W9 showing DAPI (A), TUBB3 (B), SOX10 (C), and S100B (D) and the merged image (E). The spiral ganglion is delineated by the dotted line. (F–H) Confocal images of a cochlea at W9 showing the cochlear nerve (F), the spiral ganglion in the upper basal turn (G), and the spiral ganglion in the lower basal turn (H), delineated with dotted lines and immunostained with antibodies against SOX9 and TUBB3. Cell nuclei were visualized with DAPI. Abbreviations: B1, lower basal turn; B2, upper basal turn; SG, spiral ganglion. Scale bar = 100 µm.
