Results
Specimen 1B E13.25: embryonic day 13.25; Six1tm1Mair/Six1+ (more )
Structure Level Pattern Image Note
TS21: cochlea epithelium Present Regionally restricted 1B E13.25 Expression disappeared in the postmitotic progenitors within the prosensory domain.

Specimen 1B E13.5 basal: embryonic day 13.5; Six1tm1Mair/Six1+ (more )
Structure Level Pattern Image Note
TS21: cochlea epithelium Present Regionally restricted 1B E13.5 basal Expression was only observed in a single column of cells at the medial border of the prosensory domain near the basal cochlea duct where inner hair cells will appear, but not in the apical or medial regions.

Specimen 1B E13.5 apical: embryonic day 13.5; Six1tm1Mair/Six1+ (more )
Structure Level Pattern Image Note
TS21: cochlea epithelium Present Regionally restricted 1B E13.5 apical Expression was only observed in a single column of cells at the medial border of the prosensory domain near the basal cochlea duct where inner hair cells will appear, but not in the apical or medial regions.

Specimen 1B E13.5 WM: embryonic day 13.5; Six1tm1Mair/Six1+ (more )
Structure Level Pattern Image Note
TS21: cochlea epithelium Present Regionally restricted 1B E13.5 WM Expression was only observed in a single column of cells at the medial border of the prosensory domain near the basal cochlea duct where inner hair cells will appear, but not in the apical or medial regions.

Specimen 1B E14.5 basal: embryonic day 14.5; Six1tm1Mair/Six1+ (more )
Structure Level Pattern Image Note

Specimen 1B E14.5 apical: embryonic day 14.5; Six1tm1Mair/Six1+ (more )
Structure Level Pattern Image Note
TS22: cochlea epithelium Present Regionally restricted 1B E14.5 apical Expressed in the medial border of the prosensory domain where inner hair cells develop near the basal cochlea duct.

Specimen 1B E14.5 WM: embryonic day 14.5; Six1tm1Mair/Six1+ (more )
Structure Level Pattern Image Note
TS22: cochlea epithelium Present Regionally restricted 1B E14.5 WM Expression domain extended toward the apex, but its expression was not observed in the apical end.
