| Type | developmental stage | Description | Expression was first detected at 11 dpc throughout the surface of the embryo, and it was most intense in the head region on the surfaces of the mandibular, maxillary, and frontonasal processes. At 11.5 dpc expression is detected in the first and second branchial arches, pharynx and metanephros. At 12 dpc-14 dpc, expression was intense and strikingly confined to developing ectodermal organs. The vibrissae, tylotrich hair follicles, tongue papillae, and tooth germs as well as the ear auricle. Also expressed intensely in kidney epithelium in the stalk and tips of ureter as well as in the spermatic ducts in the testis. At 17.5 dpc strong expression was restricted to kidney tubules and ameloblasts in teeth, and moderate expression was observed in hair follicles, choroids plexus of the fourth cerebral ventricle of the brain. First detected on 12.5 dpc in interstitial cell of the testis and increased towards 14.5 dpc. On 8 dpp (day post partum) highly expression was detected in kidney and weakly in skin. |
