SciVee - nasal cavity en Role of the Neural Crest in Vertebrate Development and Evolution - Part 2: The Role of the Neural Crest in Head Development and in Vertebrate Evolution (30:04) <p>The Q/C (quail/chick) marker system revealed that apart from the peripheral nervous system (PNS), the melanocytes and some endocrine tissues, the NC plays a major role in the construction of the vertebrate head. The entire facial skeleton and part of the skull (frontal, squamosal, parietal bones) are of NC origin together with the connective tissues of the face and ventral part of the neck. The contribution of the NC to the heart and blood vessel wall (except for the endothelial cells) was also demonstrated.</p> <div class="og_rss_groups"><ul class="links"><li class="first last og_links"><a href="/node/10295" class="og_links">iBioseminars</a></li> </ul></div><p><a href="">read more</a></p> adenohypophysis amphioxus anterior neural plate auditory apparatus birds blood vessels cells cephalic NCC cephalic NCC migration cephalochordates Chaya Kalcheim chick chick-quail chimeras chimeric tissues chordates CNRS and Coll College de France connective tissues Coturnix coturnix japonica craniofacial development dermis developing brain Developmental Biology diencephalon digestive track embryogenesis epiphysis epithelio-mesenchymal eye eyelid ectoderm facial skeleton facial structures forebrain Gallus gallus gene gill slits gonads gut Head Development heart hox gene expression hox negative domain hox positive domain hypothalamus interphase nucleus isthmic cells jaw light sensitivity meninges misencephalon monoclonal antibodies mouth muscle segments nasal cavity nasofrontal ectoderm NC neural crest neural folds neural tube Nicole Le Douarin notochord Olfactory placode optic placode Paris pharyngeal basket pharyngeal glands posthypophysis predation quail quail posterior diencephalic neural fold retina rostrum sense organs Smell striated muscles telencephalon tissue Vertebrate Development Vertebrate embryo Vertebrate Evolution vertebrate head iBioseminars Mon, 30 Mar 2009 18:57:07 +0000 video_collector 10347 at
