Embryonic Development of the First Branchial Arch

The textbook "Embryonic Development of the First Branchial Arch" by Joanna Andryszkiewicz offers a comprehensive analysis of the embryonic development of the first branchial arch in vertebrates. It examines how specific patterns of gene expression, particularly of signaling molecules and homeobox genes, influence the development of the definitive jaw. The author compares Dlx gene expression between mice and chickens, highlighting the differences in mesenchymal and epithelial gene expression. These differences may be attributed to varying cis-regulatory elements or different signaling pathways between the two species. Thus, the book provides valuable insights into the mechanisms of architectural pattern formation and their evolutionary significance.
