Proteins in growth regulation during early development of the chick embryo. Progress report, May 1975--May 1976
Previous studies have shown that the growth of embryo regions and the synthesis of specific proteins in embryo regions were altered when early chick embryos were cultured on various nutrient proteins. Because nutrient proteins were degraded to constituent amino acids within the yolk-sac and did not reach the embryo proper as intact macromolecules, we have been evaluating the role of the yolk-sac in the regulation of early embryonic growth and development. The synthesis of serum proteins by the yolk-sac was observed to start as early as the primitive streak stage of development. The relative synthesis of the individual serum proteins was found to change with development, with changes in protein nutrition, and with drug induced developmental abnormalities.
