Results
Specimen 2J: embryonic day 12.0 (more )
Structure Level Pattern Image Note
TS20: palatal shelf mesenchyme Present Regionally restricted 2J Expression localized to all regions of palatal mesenchyme, with increased expression within nasal and medial portions of central mesenchyme, and in lateral mesenchyme
TS20: dental placode Present Regionally restricted 2J Enhanced expression within oral and presumptive tooth germ basement membrane.
TS20: oral epithelium Present Regionally restricted 2J Enhanced expression within oral and presumptive tooth germ basement membrane.

Specimen 2K: embryonic day 13.0 (more )
Structure Level Pattern Image Note
TS21: palatal shelf mesenchyme Strong Regionally restricted 2K Expression enhanced in nasal, adjacent dorsal medial, central and maxillary mesenchyme. Expression absent from mid-oral mesenchyme and lateral mesenchyme.
TS21: palatal shelf epithelium Present Regionally restricted 2K Increased expression within nasal and oral basement membrane.

Specimen 2L: embryonic day 14.0 (more )
Structure Level Pattern Image Note
TS22: palatal shelf mesenchyme Strong Widespread 2L Increased expression within all regions of palatal mesenchyme, including ventral medial, mid-oral and lateral regions, and medial mesenchyme surrounding regressing palatal seam.

Specimen gd 14-fused not shown: embryonic day 14.0 (more )
Structure Level Pattern Image Note
TS22: palatal shelf mesenchyme Weak Widespread Decreased expression within palatal mesenchyme, distributed throughout all regions of mesenchyme.
