About This Title The Eighth Edition of Developmental Biology expands its coverage of the mechanisms of development, the roles that environmental factors play in development, the medical applications of our knowledge of development, and the roles that development plays in evolution, highlighting all the incredible advances that have been made in the last three years. Written primarily for undergraduate biology majors, it also serves to introduce graduate students and medical students to developmental biology. Eighth Edition Features and Supplements A completely updated text integrates classical developmental biology with contemporary techniques, including new material on: stem cells niches; microRNAs; sperm-egg attraction and binding; induction and maintenance of pluripotency; pioneer transcription factors and the recruitment of nucleosome remodeling proteins; left-right gene expression asymmetry; heart chamber specification; neural crest cell specification and differentiation; somite formation; human brain growth genes; the syndetome; new sources of muscle precursor cells; newly discovered mechanisms of teratogenesis; the effects of endocrine disruptors on human development; sex determination pathways in the brain; the effects of maternal nutrition on gene expression and disease susceptibility in the adult offspring; controversies over digit specification in birds and dinosaurs and whether mammalian blastomere fate is biased at the first division; and much more.
