Changing Syntheses in Development covers the proceedings of the 29th Symposium on ""The Society for Developmental Biology"", held in Albany, New York on June 17-19, 1970. This book is organized into three parts encompassing nine chapters that summarize the changing syntheses during cell and tissue interactions and its interactions to molecular biology, ultrastructure, and morphogenesis.
The book initially examines the number of copies and kinds of DNA-like RNA that are synthesized in the nuclei and conserved in the cytoplasm during early development of the frog embryo, Rana pipiens. The following chapter tackles the aspects of energy metabolism on rat embryo at somite stages. A chapter focuses on cell differentiation control in green flagellate Volvox. The second part of the book deals with the general aspects of hormone action, as they relate to problems of development. This part describes a systematic technique for the isolation of hormone-dependent cell strains from corresponding hormone-dependent animal tumors. The concluding part focuses on the use of bone matrix as a morphogenetic substratum. This part also describes the differences in the morphology between collagen fibrils of adult and embryonal connective tissue and the effect of extra- and intracellular factors on the maintenance and formation of epithelial morphology.
Developmental and molecular biologists and researchers will greatly benefit from this book.
