Results
Specimen 3D: embryonic day 9.5 (more )
Structure Level Pattern Image Note
TS15: atrioventricular canal Present 3D
TS15: outflow tract Present Regionally restricted 3D Expression is in the proximal outflow tract.
TS15: primitive ventricle cardiac muscle Present Regionally restricted 3D Expression is at the inner curvature and is up-regulated at the outer curvature.
TS15: common atrial chamber cardiac muscle Absent 3D
Specimen 5A: embryonic day 8.5 (more )
Structure Level Pattern Image Note
TS13: heart Present Graded 5A Expression is in a bilateral gradient along the anterior/posterior axis. The center is at the middle ventricular region and the gradient encompasses both dorsal and ventral sides.
