Specimen 4F/J: embryonic day 17.5 (more )
Structure Level Pattern Image Note
TS25: impulse conducting system Present Regionally restricted 4F , 4J Expression is present in the left region and in the longitudinally organized trabecules that will form the bundle branches.
TS25: interventricular septum Present Regionally restricted 4F , 4J Expression is present in the left region and in the longitudinally organized trabecules that will form the bundle branches.
TS25: left ventricle cardiac muscle Present Regionally restricted 4F , 4J Expression is present in the trabecules.
TS25: right ventricle cardiac muscle Present Regionally restricted 4F , 4J Expression is much more restricted than in the left ventricle.
TS25: atrioventricular bundle Weak 4J , 4F
