Figure 6

Early (E8.5) SOX2 expression maps to both the cochlea and vestibular ganglia whereas later (E12.5) SOX2 expression maps to the glia. (A) Schematic of the early (E8.5) SOX2 fate-mapping timeline. (B,B”) Representative sections showing E8.5 tdT fate-mapped SOX2 expression in the SG and VG (C,C”) at E14.5. Note that tdT reporting specifically labels the neuronal cell bodies in both ganglia. (D) Schematic of the later (E12.5) SOX2 fate-mapping timeline. (E,E”) Representative sections showing E12.5 fate-mapped SOX2 expression reported with tdT in both the SG and (F,F”) VG at E14.5. Note that tdT reporting does not overlap with the neuronal cell bodies, but instead appears adjacent to the TUJ1 neuronal marker. (G,H’) Representative image showing that E8.5 SOX2-reported progenitors contribute to neuronal cell bodies in both the SG and VG at E14.5, and does not overlap with the glia cell marker, SOX10. In contrast (I,J’) show representative images where E12.5 SOX2 fate-mapped progenitors contribute nearly exclusively to SOX10 labeled glial cells in both the SG and VG. Scale bar: 50 μm.
