Book Description: This volume collates the work of researchers in the field of vertebrate development. It emphasizes the role of cell to cell signalling by both diffusible signals and direct contact. Major topics covered include morphogenesis (molecular basis of organ development) and molecules and genes involved in the control of development. This book should serve as a useful introduction to those entering this field of research. It should also be of interest to molecular, cell and developmental biologists, neurobiologists and geneticists.
