Results
Specimen 8A: embryonic day 12.5 (more )
Structure Level Pattern Image Note
TS20: embryo mesenchyme Strong Regionally restricted 8A High level expression in a thin, uniform band of mesenchymal cells around the entire embryo, immediately beneath the outer primitive ectodermal covering.
TS20: epidermis Absent 8A No expression in epidermal cells overlying expressing mesenchymal cells.
TS20: face mesenchyme Strong Regionally restricted 8A Strong expression in deeper mesenchymal cells of developing facial structures.
TS20: mandible primordium Present 8A
TS20: maxilla Present 8A
TS20: tongue Present 8A
TS20: paraxial mesenchyme Strong Regionally restricted 8A Strong expression in anterior paravertebral mesenchymal tissue.
TS20: genital tubercle mesenchyme Strong 8A
TS20: pericardium Strong 8A
TS20: intestine epithelium Absent 8A
TS20: lung epithelium Absent 8A
TS20: heart Absent 8A Authors report no expression in endodermally-derived tissues of the thoracic or abdominal organs, including the liver and heart.
TS20: liver Absent 8A Authors report no expression in endodermally-derived tissues of the thoracic or abdominal organs, including the liver and heart.
TS20: nervous system Absent 8A No expression in developing neural cells.

Specimen 8B: embryonic day 12.5 (more )
Structure Level Pattern Image Note
TS20: trunk mesenchyme Present Regionally restricted 8B Expression in broad zone of lateral mesenchymal tissue, particularly around the developing neural tube, corresponding to developing dermatome tissue. No expression in more medial mesenchymal tissue adjacent to the neural tube.
