doi: 10.4081/ejh.2025.4189

Figure Lengend Snippet: Figure 1. S100β immunolabeling in the mouse cochlea at E17 and E18.5. A-C) In the mouse cochlea at E17, S100β immunoreactivity was only observed in the external cochlear wall (arrowheads), with no labeling detected in other cochlear tissues. Double-labeling with S100β and Sox2 revealed that no S100β immunoreactivity was present in the Sox2-immunoreactive auditory epithelium. D-I) In the mid- dle turn of the mouse cochlea at E18.5, S100β immunoreactivity was predominantly detected in the apical region of the developing pillar cells. S100β-labeled pillar cells were located between the Sox2-labeled IHCs and the first row of OHCs. The base of the pillar cells was also labeled with S100β. Additionally, the stria vascularis showed immunoreactivity for S-100β.

A) A low-magnification view of cross-sections of the P1 mouse cochlea labeled with S100β (red) and Sox2 (green) at P1. S100β immunoreactivity was not detected in the organ of Corti in the apical turn at P1. B,C) In the middle turn of the P1 cochlea, the stria vascularis and pillar cells of the organ of Corti were S100β-labeled. D,E) Co-staining S100β with phalloidin (red) and Sox2 (green) revealed that S100β-labeled inner and outer pillar cells were positioned at the boundary between the phalloidin-marked IHCs and OHCs. S100β-positive cells were predominantly observed in the head and foot plates of the pillar cells. F) S100β expression was also detected in the spiral limbus. G-I) Double-labeling with S100β (green) and IB4 (red) demonstrated that S100β-positive cells in the stria vascularis were in close proximity to IB4-marked intrastrial capillaries.

Figure Lengend Snippet: Figure 3. S100β immunolabeling in the mouse cochlea at P6. A-B) At the middle turn of the P6 cochlea, S100β staining was present throughout the cell bodies of both inner and outer pillar cells, which were separated to form the tunnels of Corti. The apices of the S100β- expressing pillar cells projected laterally (arrowhead) to contact the OHCs. Labelling for S100β was observed in the three rows of Deiters’ cells, with S100β-expressing Deiters’ cells positioned at the base of each OHC, extending a long phalangeal process (arrows) between the base and the apex of the OHCs. C) S100β labeling was also seen in the spiral limbus. D) Double-labeling of S100β with phalloidin showed that S100β-labeled Deiters’ cell phalangeal processes extending between rows of OHCs. E,F) S100β expression was localized to strial marginal cells facing the scale media, S100β colocalized with phalloidin in the basal cells of the stria vascularis. G-I) strial intermediate cells that located around the IB4-labeled strial capillaries were immunopositive for S100β. J-L) In both the apical and basal turns of the P6 cochlea, S100β was also expressed in the outer and inner pillar cells and the three rows of Deiters’ cells.

Figure Lengend Snippet: Figure 5. S100β immunolabeling in the mouse cochlea at P10 and P12. A-C) At P10, double staining of S100β and phalloidin revealed that S100β-labeled Deiters’ cell phalangeal processes were clearly located below the phalloidin-stained cuticular plate of OHCs. S100β expression was also observed in the Deiters’ cups (arrowheads), which held the OHCs at their base. Notably, the center of the head region of pillar cells, rich in phalloidin-marked actin, was unlabeled for S100β. D-I) At P12, S100β-expressing cells were observed in the inner and outer pillar cells, the soma and phalangeal processes of the Deiters’ cells, the spiral limbus, the stria vascularis, and the spiral ligament. The Deiters’ cups (arrowheads) were also immunoreactive for S100β.

D-F) S100β staining in the phalangeal processes of Deiters’ cells was ambiguous, although the bodies and cups (arrowheads) of the Deiters’ cells remained immunoreactive. G-I) At P21, phalloidin-marked actin labeling was prominent in the pillar cell foot and head, as well as in the Deiters’ cups.
