• neural crest
  3 November 2003

  Neural crest cells are a group of cells that migrate from the opposing epithelial folds of the closing neural tube in the back of the embryo to a number of positions inside the embryo.
  These cells contribute to the development of several organs, the heart, facial skeleton, thymus, parathyroid, adrenal medulla and the whole peripheral nervous system. Neural crest cells are also needed for a normal development of the outflow region of the heart as well as for correct architecture of the (...)
