Results
Specimen 1a/c: embryonic day 10.5 (more )
Note: The genotype could be either +/+ or +/-. Double labeled: red - Gja1; green - Hcn4 (assay MGI:7537184).
Structure Level Pattern Image Note
TS17: atrium cardiac muscle Present 1a , 1c
TS17: sinoatrial node Present Regionally restricted 1c Only marginal overlap with Hcn4-positive cells.
TS17: outflow tract cardiac muscle Present 1a
TS17: primitive ventricle cardiac muscle Present 1a

Specimen 1b/d: embryonic day 10.5; Dbhtm1Rpa/Dbhtm1Rpa (more )
Note: Double labeled: red - Gja1; green - Hcn4 (assay MGI:7537184).
Structure Level Pattern Image Note
TS17: outflow tract cardiac muscle Present 1b Staining intensity was substantially less than that observed in adrenergic-competent control hearts.
TS17: primitive ventricle cardiac muscle Present 1b Staining intensity was substantially less than that observed in adrenergic-competent control hearts.
TS17: atrium cardiac muscle Present 1b , 1d Staining intensity was substantially less than that observed in adrenergic-competent control hearts.
TS17: sinoatrial node Present 1b , 1d Staining intensity was substantially less than that observed in adrenergic-competent control hearts.

Specimen 2c/e: embryonic day 9.5 (more )
Note: The genotype could be either +/+ or +/-.
Structure Level Pattern Image Note
TS15: heart Present 2c , 2e

Specimen 2d/f: embryonic day 9.5; Dbhtm1Rpa/Dbhtm1Rpa (more )
Structure Level Pattern Image Note
TS15: heart Present 2f , 2d Similar as in the controls.

Specimen S1c/e: embryonic day 10.5 (more )
Note: The genotype could be either +/+ or +/-.
Structure Level Pattern Image Note
TS17: atrioventricular canal cardiac muscle Present S1e , S1c

Specimen S1d/f: embryonic day 10.5; Dbhtm1Rpa/Dbhtm1Rpa (more )
Structure Level Pattern Image Note
TS17: atrioventricular canal cardiac muscle Trace S1d , S1f Could be seen when image processing was adjusted to increase sensitivity.
