“…While SOX2 and MYO6 expression persist in the adult ( Figure 4G, I), LHX3 and ATOH1 expression are lost from the auditory sensory epithelium ( Figure 4H and data not shown). SOX2 expression is detected in a subset of differentiated support cells, including Deiters', pillar, inner phalangeal, tectal and lateral tunnel cells ( Figures 4G, 5C, D) (Spicer et al, 2003). Because of the three-dimensional organization of the adult organ of Corti, the full extent of SOX2 expression is best appreciated in the brightest point projection Z-series of an immunolabeled whole-mount preparation ( Figure 5C, D).…”
