It has been proposed that the  nested pattern of Dlx expression identified in mouse  first arch is conserved in gnathostomes as a common  mechanism of patterning the arch. Similar to mouse  nested expression of the Dlx genes was revealed in  chick, however, differences in the extent of the  mesenchymal expression, as well as marked  differences in the epithelial expression patterns  between these two species were observed. One  possibility to explain these differences in  expression may be attributed to differences in the  Dlx cis-regulatory elements between chick and mouse.  Another explanation is that differences in  signalling between chick and mouse account for the  differences observed in the Dlx expression patterns.  Finally genes exhibiting disparate expression in  these species like recently identified Lix1 may  offer a further mechanism by which first arch  patterning may be modulated to give species specific  first arch characteristics.\u003c\/p\u003e\u003cdiv class=\"aw-variant-hidden-subtitle-div\" id=\"aw-variant-subtitle-9783838388199\"\u003e\u003ch3\u003eGene Expression, Regulation and Patterning\u003c\/h3\u003e\u003c\/div\u003e","brand":"Autorenwelt Shop","offers":[{"title":"Softcover - 9783838388199","offer_id":39499043799133,"sku":"9783838388199","price":79.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0622\/files\/c1bc71c2-f68b-4f4b-8223-690d8b1ff5b6.jpg?v=1768893166","url":"https:\/\/shop.autorenwelt.de\/products\/embryonic-development-of-the-first-branchial-arch-von-joanna-andryszkiewicz","provider":"Autorenwelt Shop","version":"1.0","type":"link"}
