  • Title: Development of the limb neuromuscular system.
    Author: Sharma K, Izpisúa Belmonte JC.
    Journal: Curr Opin Cell Biol; 2001 Apr; 13(2):204-10. PubMed ID: 11248554.
    Abstract:
    Appendages, such as wings of a fly or limbs of a vertebrate, are excellent models to study the principles of patterning and morphogenesis. In the adult these structures are used for a variety of behaviors, including locomotion. Although support structures of the adult vertebrate limb are generated within the limb bud, its dynamic elements are derived from the somitic mesoderm and neural tube. Recent studies show that regional patterns set up in the mesenchyme-filled limb bud guide muscle precursors and developing motor axons to their proper location within the limb. Subsequent development of the neuromuscular system is regulated by cell surface interactions between pre-specified muscle fibers and motor axons.
