Developmental Regulation: Aspects of Cell Differentiation draws together some studies which are directed toward the orderly changes in cell phenotypes that are understood to be developmental in nature. Organized into nine chapters, the book begins with a concise overview of the studies on molecular synthesis during early development. It then addresses the developmental regulation in cotton seed embryogenesis and germination; relation of hormonal regulation to the possible control of RNA and protein biosynthesis; transitions in differentiation by the cellular slime molds; and interrelationships of genes, enzymes, structures, and phenotypes in morphogenesis. It also explains the colony differentiation in green algae; cytology of developing vertebrate skeletal muscle; some comparative aspects of cardiac and skeletal myogenesis; and differentiation of cartilage in the limb.
