Results
Specimen 5C: embryonic day 8.5 (more )
Note: Data for +/+ or +/- embryos were indistinguishable and are referred to as 'wild-type'; thus the pictured specimen could have been a heterozygous animal.
Structure Level Pattern Image Note
TS13: node Present 5C
TS13: notochord Present 5C

Note: Data for +/+ or +/- embryos were indistinguishable and are referred to as 'wild-type'; thus the pictured specimen could have been a heterozygous animal.
Structure Level Pattern Image Note
TS13: node Present 5C'
TS13: notochord Present 5C'

Specimen Heterozygote: embryonic day 8.5; Tcf7l1tm2Efu/Tcf7l1+ (more )
Structure Level Pattern Image Note

Specimen 5G: embryonic day 8.5; Tcf7l1tm2Efu/Tcf7l1tm2Efu (more )
Note: This mutant appears to have axis duplications on opposite sides of the embryo.
Structure Level Pattern Image Note

Note: This mutant appears to have axis duplications on opposite sides of the embryo.
Structure Level Pattern Image Note
TS13: primitive streak Present 5G' This embryo appears to have a primary and secondary primitive streak.
TS13: node Present 5G' Expression is often grossly expanded in the mutant, as a direct reflection of the degree of expanded/duplicated node and notochordal cells in a given embryo.
