Abstract
Metabolic regulation is critical in embryonic development and influences key processes such as fertilization, zygotic genome activation, cell compaction, implantation, gastrulation and organ development. Here we explore the interplay between metabolism and embryonic development in the context of important sequential key embryonic events, highlighting the orchestration of developmental processes by various metabolites and signalling molecules. Key metabolites, including glucose, fatty acids and amino acids, act as modulators of developmental processes, while also serving as energy sources and building blocks for cellular structures. Understanding the intricate relationship between metabolism and embryogenesis may provide insights into developmental disorders and potential therapeutic interventions.
