Temporally and spatially restricted expression of the helix-loop-helix transcriptional regulator Id1 during avian embryogenesis.
We isolated the chick orthologue of the Id1 helix-loop-helix gene and analyzed its expression pattern during early chick embryo development by whole-mount in situ hybridization. The Id1 expression pattern is dynamic and confined to discrete locations including the neural plate border, prospective olfactory placode, hindbrain, mesenchyme of distal branchial arches and adjacent to placodes, and the distal mesoderm of the limb buds.
