Vertebrate Myogenesis

The development of vertebrate muscle has long been a major area of research in developmental biology. During the last decade, novel technical approaches have allowed us to unravel to a large extent the mechanisms underlying muscle formation, and myogenesis has arguably become one of the best-understood paradigms for cellular differentiation. This book concisely summarizes our current knowledge about muscle development in vertebrates, from the determination of muscle precursors to terminal differentiation. Each chapter has been written by an expert in the field, and particular emphasis has been placed on the different developmental and molecular pathways followed by the three types of vertebrate musculature - striated, heart and smooth muscle.

Concise description of vertebrate myogenesis Incorporates latest findings on control of smooth muscle development Edited and written by experts in the field Includes supplementary material: sn.pub/extras
