Mesoderm and jaw development in vertebrates: the role of growth factors

The head and neck arise during development as the result of a complex
series of cellular and molecular interactions that begin in the fertilized
egg. In this article, the role of an important class of molecules, growth
factors, is examined in two main steps of the developmental sequence: the
initial induction of mesoderm and the later induction of jaw cartilage and
bone. The article focuses particularly on the roles of members of the
transforming growth factor-beta (TGF-beta), fibroblast growth factor (FGF),
and epithelial growth factor (EGF) families in these processes and current
models of growth factor involvement. Possible experiments for the future
are discussed.
