Reference: J:54908 Houzelstein D, et al., The homeobox gene Msx1 is expressed in a subset of somites, and in muscle progenitor cells migrating into the forelimb. Development. 1999 Jun;126(12):2689-701
Assay type: RNA in situ
MGI Accession ID: MGI:1336739
Gene symbol: Pax3
Gene name: paired box 3
Probe: Pax3 probe10
Visualized with: Alkaline phosphatase
Results
Specimen 1.a: embryonic day 9.5 (more )
Note: 25 somite stage.
Structure Level Pattern Image Note
TS15: trunk dermomyotome Present Regionally restricted 1a Expression is seen in muscle progenitor cells that have left somites 9-12 at the level of the forelimb bud.
Specimen 1.b: embryonic day 9.5 (more )
Note: 29 somite stage.
Structure Level Pattern Image Note
TS15: forelimb bud Present Regionally restricted 1b Positive cells are dermomyotomal cells that are located in the proximal part of the forelimb, adjacent to somites 9-14.
Specimen 1.c: embryonic day 10.0 (more )
Note: 32 somite stage.
Structure Level Pattern Image Note
TS16: hindlimb bud Present Regionally restricted 1c Expressing cells have begun to delaminate from somites 26-29.
Specimen 1.d: embryonic day 10.5 (more )
Note: 36 somite stage.
Structure Level Pattern Image Note
TS17: hindlimb bud Present Regionally restricted 1d Expressing cells have begun to delaminate from adjacent somites to locate within the proximal part of the hindlimb bud.
Specimen 1.e: embryonic day 10.5 (more )
Note: 38 somite stage.
Structure Level Pattern Image Note
TS17: forelimb bud Present Regionally restricted 1e Expressing cells have migrated from adjacent somites into forelimb bud.
Specimen 1.f: embryonic day 11.0 (more )
Note: 40 somite stage.
Structure Level Pattern Image Note
TS18: hindlimb bud Present Regionally restricted 1f Expressing cells comprise hindlimb premuscle mass. A few positive cells still appear to be delaminating from somites 27,31 and 32.
Specimen 2d inset: embryonic day 9.75; Msx1tm1Bero/Msx1tm1Bero (more )
Note: 30 somite stage.
Structure Level Pattern Image Note
TS16: trunk dermomyotome Present Regionally restricted 2d inset Expression is in the lateral region of the dermomyotome.
