metadata.name: dc.description.abstract
metadata.value: Neural crest (NC) is an established source for many endochondral and intramembranous
  bones in the skull and postcranial skeleton in vertebrates. Neural crest
  cells also contribute to the trapezius/cleidohyoideus muscle attachment sites on
  the shoulder girdle of the mouse, where they are found in the scapula, clavicle,
  and sternum. In the avian shoulder girdle, NC cells from the level of the first two
  cranial−most somites were only found so far in the clavicle, while in the axolotl, the
  NC contribution to the shoulder girdle was not found at all. In this study we aimed
  to determine whether NC cells caudal to the level of the second somite contribute
  to the cartilaginous shoulder girdle in birds and to analyse the phylogenetic distribution
  of NC cells in the vertebrate shoulder girdle. Homotopic quail to chick embryos
  and GFP+ to white chick embryos transplantations of the neural tube including
  presumptive NC, as well as immunohistochemical detection of NC markers, such
  as HNK-1 and PDGFRα revealed no contribution of NC cells from somite levels
  3−27 to the skeletal elements of the shoulder girdle, including, but not restricting
  to muscle attachment sites, despite abundance of other NC derivatives. Thus, in
  birds, NC does not contribute to the formation of the cartilaginous shoulder girdle.
  The negative result is discussed in a broad evolutionary aspect. It supports the notion
  of the uniqueness of NC contribution to the variety of endochondral bones in
  mice (or mammals). In other vertebrates, including birds, only the cells of the cranial
  NC seem to migrate to the shoulder girdle and contribute to the intramembranous
  clavicles and/or interclavicle. We critically evaluate the existing hypotheses on evolution
  of NC contribution to the shoulder girdle in vertebrates.
