Results
Specimen 3E: embryonic day 9.5 (more )
Structure Level Pattern Image Note

Specimen 3F: embryonic day 9.5; Smad5tm1Cxd/Smad5tm1Cxd (more )
Structure Level Pattern Image Note
TS15: blood vessel Present 3F The mutant lacked an organized vascular network.

Specimen 3G: embryonic day 9.5 (more )
Structure Level Pattern Image Note
TS15: yolk sac Present 3G Expression was detected in endothelial cells.

Specimen 3H: embryonic day 9.5; Smad5tm1Cxd/Smad5tm1Cxd (more )
Structure Level Pattern Image Note
TS15: yolk sac Present 3H Expression was detected in endothelial cells.

Specimen not shown wild type: embryonic day 8.5 (more )
Structure Level Pattern Image Note
TS14: vascular plexus Present Regionally restricted Expression was detected in the primitive vascular plexus in the developing brain.

Specimen not shown mutant: embryonic day 8.5; Smad5tm1Cxd/Smad5tm1Cxd (more )
Structure Level Pattern Image Note
TS14: vascular plexus Present Regionally restricted Expression was detected in the primitive vascular plexus in the developing brain of the mutant, which was indistinguishable from wild type.

Specimen 7A: embryonic day 9.5 (more )
Structure Level Pattern Image Note
TS15: vascular plexus Present Regionally restricted 7A Expression was detected in the vascular network in the developing brain.

Specimen 7B: embryonic day 9.5; Smad5tm1Cxd/Smad5tm1Cxd (more )
Structure Level Pattern Image Note
TS15: vascular plexus Present Regionally restricted 7B The mutant vascular network was simplified and abnormal compared to wild type.

Specimen 7C: embryonic day 9.5 (more )
Structure Level Pattern Image Note
TS15: blood vessel Present Regionally restricted 7C Expression was detected in the blood vessels in the limb.

Specimen 7D: embryonic day 9.5; Smad5tm1Cxd/Smad5tm1Cxd (more )
Structure Level Pattern Image Note
TS15: blood vessel Present Regionally restricted 7D Blood vessels were enlarged and misshapen in the mutant limb.
