Results
Specimen 1A Brachial: embryonic day 13.5 (more )
Note: Flat-mounted specimen.
Structure Cell Type Level Pattern Image Note
TS21: spinal cord brachial region spinal cord motor neuron Present Regionally restricted 1A Sema3D Brachial Expression is in motoneuron subpopulations, with little or no expression in other cell types. Expression is in medial parts of the median motor column and in some motoneurons in the most rostral part of brachial lateral motor columns.
Specimen 1A Brachial section: embryonic day 13.5 (more )
Structure Cell Type Level Pattern Image Note
TS21: spinal cord brachial region spinal cord motor neuron Present Regionally restricted 1A Sema3D Brachial section Expression is in motoneuron subpopulations, with little or no expression in other cell types.
Specimen 1A Lumbar: embryonic day 13.5 (more )
Note: Flat-mounted specimen.
Structure Cell Type Level Pattern Image Note
TS21: spinal cord lumbar region spinal cord motor neuron Present Regionally restricted 1A Sema3D Lumbar Expression is in motoneuron subpopulations, with little or no expression in other cell types.
Specimen 2F: embryonic day 13.5 (more )
Note: Double labeled: blue - Sema3d; brown - Etv4 reporter (assay MGI:7615027).
Structure Cell Type Level Pattern Image Note
TS21: spinal cord brachial region spinal cord motor neuron Present Regionally restricted 2F Expression is in a motoneurons subpopulation in the medial part of the lateral motor columns in the most rostral part of the brachial spinal cord.
