Specimen 2a: embryonic day 12.5 (more )
Structure Level Pattern Image Note
TS20: cochlear duct Present Regionally restricted 2a Expression is present at the basal end.

Specimen 2c: embryonic day 13.5 (more )
Structure Level Pattern Image Note
TS21: cochlear duct Present Graded 2c Expression is present in the basal but not in the apical turn.

Specimen 2e: embryonic day 14.5 (more )
Structure Level Pattern Image Note
TS22: cochlea Present Non-Uniform 2e Expression is present in the basal, middle, and apical profile. A broad band of expression encompasses most of the greater epithelial ridge and a narrow band is positioned where the lesser epithelial ridge begins to thin into a cuboidal epithelial layer.

Specimen 3a: postnatal day 1 (more )
Structure Level Pattern Image Note
TS27: cochlea Present Non-Uniform 3a A broad band of expression encompasses most of the greater epithelial ridge and a narrow band is positioned where the lesser epithelial ridge begins to thin into a cuboidal epithelial layer. Cells which will form interdental cells do not express.

Specimen 3c: postnatal day 8 (more )
Structure Level Pattern Image Note
TS28: cochlea Present Regionally restricted 3c Expression is no longer detected in the basal coil of the cochlea.

Specimen 4a: embryonic day 14.5 (more )
Structure Level Pattern Image Note
TS22: cochlea Present Non-Uniform 4a A broad band of expression encompasses most of the greater epithelial ridge and a narrow band is positioned where the lesser epithelial ridge begins to thin into a cuboidal epithelial layer.

Specimen 4c: postnatal day 1 (more )
Structure Level Pattern Image Note
TS27: cochlea Present Non-Uniform 4c A broad band of expression encompasses most of the greater epithelial ridge and a narrow band is positioned where the lesser epithelial ridge begins to thin into a cuboidal epithelial layer.

Specimen 4e: postnatal day 8 (more )
Structure Level Pattern Image Note
TS28: cochlea Absent 4e Expression is absent in all regions of the cochlea as the greater epithelial ridge recedes to form the internal sulcus.
