Results
Specimen 1C right: embryonic day 9.5 (more )
Structure Level Pattern Image Note
TS15: unsegmented mesenchyme Present Regionally restricted 1C right Expressed in a single stripe located at a distance of one somite length posterior to the transition between presomitic mesenchyme and condensed somites (S-I entire or its anterior half).
Specimen 1D: embryonic day 9.5 (more )
Note: Double labeled: red - Mesp2; magenta - Hoxd1 (assay MGI:7640042).
