Metabolism is the cornerstone of life, orchestrating the myriad chemical reactions that sustain cells, tissues, and organisms. It drives growth, division, energy production, and cellular maintenance. For scientists, understanding metabolism, particularly during the earliest stages of human development, holds the key to uncovering the origins of various diseases and developmental disorders. However, studying metabolism in human embryos presents formidable challenges due to ethical considerations, their tiny size, and the intricate web of metabolic pathways. In a groundbreaking study, researchers Prof. Andisheh Dadashi and Derek Martinez of the University of New Mexico-Valencia leveraged advanced computational models to shed light on the metabolic processes occurring in human embryos during the critical peri-implantation stage.
