| Type | developmental stage | Description | Expressed throughout pituitary development. Not found in 8 dpc embryos but seen in embryos at 8.5 dpc in the region of the first branchial arch and ventral portion of the caudal-most region of the embryo. At 9.5 dpc observed in the hindlimb buds, maxillary and mandibular components of the first branchial arch and Rathke pouch and the pattern of expression continues through 10.5 dpc at 11.5 dpc also found in ventral mesenchyme covering the abdominal cavity and in the nasal epithelium. At 17.5 dpc expressed in derivatives of the first branchial arch, including tongue and mandible as well as duodenum, salivary glands, nasal epithelium and condensing cartilage in the hindlimbs. |
