Reference: J:73068 Spassky N, et al., Sonic hedgehog-dependent emergence of oligodendrocytes in the telencephalon: evidence for a source of oligodendrocytes in the olfactory bulb that is independent of PDGFRalpha signaling. Development. 2001 Dec;128(24):4993-5004
Assay type: RNA in situ
MGI Accession ID: MGI:2157536
Gene symbol: Olig2
Gene name: oligodendrocyte transcription factor 2
Probe: pBRAH16
Probe preparation: Antisense labelled with digoxigenin RNA
Assay notes: The authors stated that they did in situ hybridizations using probes for Olig1 and Olig2 and saw similar patterns of expression; it is unclear which probe was used to stain the specimens pictured in Figure 6.
Results
Specimen 6A: embryonic day 14.5 (more )
Structure Level Pattern Image Note
TS22: medial ganglionic eminence Present Regionally restricted 6A Mostly in the ventricular layer although there is some expression in scattered cells in the marginal layer.
TS22: olfactory lobe Absent 6A There is no expression in the olfactory bulb.
Specimen 6B: embryonic day 16.5 (more )
Structure Level Pattern Image Note
TS24: olfactory lobe Present Single cells 6B Expression is present in a few scattered cells of the olfactory bulb ventricular zone.
Specimen 6C: postnatal day 3 (more )
Structure Level Pattern Image Note
TS27: main olfactory bulb Present Regionally restricted 6C Expression is abundant mainly in the marginal layer and undetectable in the ventricular zone.
